Pre-Algebra Story Problem.

Question

A store window has a perimeter of 18 feet. The width is 6 feet. Find the length and the area.

Answer 1

Perimeter = P = L + W + L + W = 2L + 2W

2L + 2W = 18 feet

W = 6 feet

2L + 2x6 = 18

2L + 12 = 18

2 L = 6

L = 3 feet = length of window

 

Area = A = LxW

3 x 6 = 18 square feet
