Example Question #142 : How To Find The Perimeter Of A Rectangle

Use the following to answer the question.

Rectangle1

Find the perimeter of the rectangle.

Possible Answers:

Correct answer:

Explanation:

To find the perimeter of a rectangle, we use the following formula:

where a, b, c, and d are the lengths of each side of the rectangle.

 

When we look at the rectangle

Rectangle1

we know that the length is 9ft and the width is 4ft.  Because it is a rectangle, we also know the lengths of the unmarked sides.  The unmarked sides are equal to the length of the opposite side.  So, we can substitute this into the formula.  We get

Example Question #511 : Rectangles

Find the perimeter of the rectangle.

A rectangle has a length of 12cm and a width of 4cm. What is the perimeter of this rectangle.

Possible Answers:

Correct answer:

Explanation:

To find the perimeter of a rectangle, you must first understand that a rectangle's opposite sides are equal. Therefore if you know the length of one side it is the identical length of the opposite side.

32cm is your answer.

Example Question #512 : Rectangles

Find the perimeter of a rectangle.

A rectangle has a width of 7cm and a length of 10cm. What is the perimeter of the rectangle?

Possible Answers:

Correct answer:

Explanation:

First you need to understand that opposite sides of a rectangle are equal. Then you are able to add the value of each side to itself and then add your sums together to get the perimeter of a rectangle.

Example Question #581 : Geometry

Use the following rectangle to answer the question:

Rectangle1

Find the perimeter.

Possible Answers:

Correct answer:

Explanation:

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.

Rectangle1

We can see the length is 6in.  Because it is a rectangle, the opposite side is also 6in. 

We can also see the width of the rectangle is 3in. Because it is a rectangle, the opposite side is also 3in.

Knowing this, we can substitute into the formula.  We get
