Example Question #54 : How To Find The Area Of A Rectangle
Find the area of a rectangle with a length of 8cm and a width of 6cm.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the length of the rectangle is 8cm. We also know the width of the rectangle is 6cm. Knowing this, we can substitute into the formula. We get
Example Question #86 : Geometry
Use the following rectangle to answer the question:
Find the area.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, let's look at the rectangle.
We can see the length is 6 inches. We can also see the width is 3 inches.
Knowing this, we can substitute into the formula. We get
Example Question #55 : How To Find The Area Of A Rectangle
Find the area of a rectangle with a width of 5cm and a length that is two times the width.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the width of the rectangle is 5cm. We also know the length is two times the width. Therefore, the length is 10cm.
Knowing this, we can substitute into the formula. We get
Example Question #71 : Plane Geometry
Use the following image to answer the question:
Find the area.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, given the rectangle
We can see the length is 9cm. We can also see the width is 7cm.
Knowing this, we can substitute into the formula. We get
Example Question #51 : How To Find The Area Of A Rectangle
Use the following rectangle to answer the question:
Find the area.
To find the area of a rectangle, we will use the following equation:
where l is the length and w is the width of the rectangle.
So, given the rectangle
we can see the length is 11in and the width is 5in.
Knowing this, we can substitute into the formula. We get
Example Question #1021 : Isee Lower Level (Grades 5 6) Mathematics Achievement
Find the area of a rectangle with a width of 3cm and a length that is four times the width.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the width of the rectangle is 3cm. We also know the length is four times the width. Therefore, the length is 12cm.
Knowing this, we will substitute into the formula. We get
Example Question #61 : Rectangles
Find the area of a rectangle with a length of 16in and a width that is half the length.
To find the area of a rectangle, we will use the following formula:
where l is the length and w is the width of the rectangle.
Now, we know the length of the rectangle is 16in. We also know the width is half of the length. Therefore, the width is 8in.
Knowing this, we can substitute into the formula. We get
