Question

A rectangle has a perimeter of 66 meters and a height of 14.2 meters. What is the length of the base?

Answer 1

Hey there! I'm happy to help!

The perimeter is the distance around the rectangle. You have used the word height, but I will replace it with the word width because the word height is usually used with 3D shapes.

If W is the width and the length is L, the formula for the perimeter is 2W+2L=P.

We can plug in the numbers we already have to solve for L, the length of our base.

2(14.2)+2L=66

28.4+2L=66

We subtract 28.4 from both sides.

2L=37.6

We divide both sides by 2.

L=18.8

The length of the base is 18.8 meters.

Have a wonderful day!
