Question

The width of a rectangle is five less than three times the length of the rectangle. The perimeter of the rectangle is 70 inches.

Write an expression to find the width of the rectangle, an expression to find the length of the rectangle, and an equation to show the relationship between these expressions and the perimeter of the rectangle

Answer 1

W = 3L-5

Perimeter = 70 = 2W+2L = 6L-10+2L = 8L-10

8L - 10 = 70

8L = 80'

L= 10 inches = length

W=3(10)-5 = 25 inches = width
