Question

4. A parking lot of rectangular shape has a perimeter of 420m. The width is three-fourths

of the length. What are the dimensions of the parking lot? Sketch the rectangle and show

all steps.

Answer 1

Width: 90m

Length: 120m

Explanation:

Width = 3/4x

Length = x

2(3/4x) + 2x = 420m

6/4 x + 2x = 420m. (6/4 + 2 = 7/2)

7/2x = 420m

7x = (420)*(2)

x = 840/7 = 120

Width = (120)*(3/4) = 90

Length: 120

2(90)+2(120)= 420m
