Question

The perimeter of a rectangle parking lot is 330 m if the width of the parking lot is 73 m what is it length

Answer 1

92

Explanation:

Using the formula for perimeter, 2l+2w, we can work backwards since you have one of the measurements already.

330-2(73)=184

Then divide your answer into 2 since you are looking for one side length.

184÷2=92.

Answer 2

Answer: 92 meters

Work Shown:

L = length = unknown

W = width = 73 meters

P = perimeter = 330 meters

The formula for a perimeter of a rectangle is P = 2(L+W) which is equivalent to P = 2L+2W.

I'll use the first version to solve for L.

P = 2(L+W)

330 = 2(L+73)

2(L+73) = 330

L+73 = 330/2

L+73 = 165

L = 165-73

L = 92 meters is the length
