Example Question #583 : Quadrilaterals

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

Example Question #584 : Quadrilaterals

Use the following rectangle to solve the problem:

Rectangle2

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, given the rectangle

Rectangle2

we can see the length is 11in.  Because it is a rectangle, the opposite side is also 11in.

The width is 5in.  Because it is a rectangle, the opposite side is also 5in.

So, we can substitute.
