Example Questions
Example Question #315 : Geometry And Graphs
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 l is the length and w is the width of the rectangle.
Now, given the rectangle
we can see the length is 9cm and the width is 7cm. So, we can substitute. We get
Example Question #316 : Geometry And Graphs
Find the perimeter of a rectangle with a width of 7in and a length that is two times the width.
To find the perimeter 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 7in. We know the length is two times the width. Therefore, the length is 14in. So, we can substitute. We get
Example Question #317 : Geometry And Graphs
Find the perimeter of a rectangle with a length of 
There are two congruent lengths and two congruent widths in a rectangle.
The perimeter is the sum of all length and width.
The answer is:
Example Question #318 : Geometry And Graphs
Find the perimeter of a square if the area is 60.
Write the formula for the area of a square.
Substitute the area into the equation.
Square root both sides.
Simplify both sides and factor the radical by using factors of perfect squares.
Multiply the side by four since the square has 4 congruent sides.
The answer is:
Example Question #1281 : Ged Math
If the side of a square has a length of 
The perimeter of a square is four times the length since, all four sides are congruent.
The answer is:
Example Question #321 : Geometry And Graphs
A rectangle has a diagonal of 
Notice that the question gives us the hypotenuse of a right triangle that has two sides of the rectangle as legs.
Use the Pythagorean Theorem to find the missing side of the rectangle.
Now, add together the sides to find the perimeter of the rectangle.
Make sure to round to two places after the decimal.
Example Question #31 : Squares, Rectangles, And Parallelograms
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 l is the length and w is the width of the rectangle.
Now, given the rectangle
we can see the length is 9cm and the width is 7cm. So, we can substitute. We get
Example Question #32 : Squares, Rectangles, And Parallelograms
Use the following square to answer the question:
Find the perimeter.
To find the perimeter of a square, we will use the following formula:
where a, b, c, and d are the lengths of the sides of the square.
Now, given the square
we can see one side is 8cm. Because it is a square, all sides are equal. Therefore, all sides are 8cm. So, we substitute. We get
Example Question #31 : Perimeter And Sides Of Quadrilaterals
Find the perimeter of a rectangle with a length of 12in and a width that is a third of the length.
To find the perimeter 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 12in. We know the width of the rectangle is a third of the length. Therefore, the width is 4in. So, we can substitute. We get
Example Question #32 : Perimeter And Sides Of Quadrilaterals
Find the perimeter of a square with a width of 12in.
To find the perimeter of a square, we will use the following formula:
where a is any side of the square. Because a square has 4 equal sides, we can use any side within the formula.
Now, we know the square has a width of 12in. So, we can substitute. We get
