Example Question #111 : Plane Geometry
Find the perimeter of a rectangle with a length of 14 inches and a width that is half the length.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 14 inches. Because it is a rectangle, we know the opposite side is the same length. Therefore, the opposite side is also 14 inches. We also know the width is half the length. Therefore, the width is 7 inches. Because it is a rectangle, we know the opposite side is the same length. Therefore, the opposite side is also 7 inches. Knowing this, we can substitute into the formula. We get
Example Question #131 : Geometry
Find the perimeter of a rectangle with a length of 10cm and a width that is half the length.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the base of the rectangle has a length of 10cm. Because it is a rectangle, we know the opposite side is the same length. Therefore, the opposite side is also 10cm.
We know the width is half the length. Therefore, the width is 5cm. Because it is a rectangle, we know the opposite side is the same length. Therefore, the opposite side is also 5cm.
Knowing this, we can substitute into the formula. We get
Example Question #132 : Geometry
Find the perimeter of a rectangle with a length of 10 inches and a width that is twice the length.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 10 inches. Because it is a rectangle, we know the opposite side is also 10 inches. We also know the width is twice the length. Therefore, the width is 20 inches. Because it is a rectangle, we know the opposite side is also 20 inches. Knowing all of this, we can substitute into the formula. We get
Example Question #111 : Plane Geometry
Find the perimeter of a rectangle with a length of 7cm and a width of 4cm.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 7cm. Because it is a rectangle, we know the opposite side is also 7cm. We also know the width of the rectangle iis 4cm. Because it is a rectangle, the opposite side is also 4cm. Knowing this, we can substitute into the formula.
Example Question #131 : Geometry
Find the perimeter of a rectangle with a length of 7cm and a width of 3cm.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 7cm. Because it is a rectangle, we know the opposite side is also 7cm. We know the width of the rectangle is 3cm. Because it is a rectangle, we know the opposite side is also 3cm. Knowing all of this, we can substitute into the formula. We get
Example Question #131 : Geometry
Use the following figure to answer the question:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, in the rectangle
we can see the length is 6 inches. Because it is a rectangle, we know the opposite side is also 6 inches.
We can also see the width is 3 inches. Because it is a rectangle, we know the opposite side is also 3 inches.
Knowing this, we can substitute into the formula. We get
Example Question #41 : How To Find The Perimeter Of A Rectangle
Find the perimeter of a rectangle with a length of 8cm and a width of 6cm.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, we know the length of the rectangle is 8cm. Because it is a rectangle, we know the opposite side is also 8cm.
We know the width of the rectangle is 6cm. Because it is a rectangle, we know the opposite side is also 6cm.
Knowing this, we can substitute into the formula. We get
Example Question #111 : Plane Geometry
Use the following rectangle to answer the question:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, given the rectangle
we can see the length is 11in. Because it is a rectangle, the opposite side is also 11in. We see the width is 5in. Because it is a rectangle, the opposite side is also 5in.
Knowing this, we can substitute into the formula. We get
Example Question #1071 : Isee Lower Level (Grades 5 6) Mathematics Achievement
Find the perimeter of a rectangle with a length of 9in and a width of 4in
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
So, we know the length of the rectangle is 9in. Because it is a rectangle, the opposite side is also 9in. We know the width of the rectangle is 4in. Because it is a rectangle, we know the opposite side is also 4in.
Knowing this, we can substitute into the formula. We get
Example Question #131 : Geometry
Use the following rectangle to answer the question:
Find the perimeter.
To find the perimeter of a rectangle, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the rectangle.
Now, let's look at the rectangle.
We can see the length is 11 inches. Because it is a rectangle, the opposite side is also 11 inches. We can see the width is 5 inches. Because it is a rectangle, the opposite side is also 5 inches.
Knowing this, we can substitute into the formula. We get
