The area of a rectangle is 54 square

meters. The width of the rectangle is

three meters more than the length. What

are the dimensions of the rectangle?

Width = 9 meters Length = 6 meters

Step-by-step explanation:

9 times 6 is 54

9 is 3 meters longer than 6 so 9 is the width.

This means 6 is the length

w = 6 m

l = 9 m

Step-by-step explanation:

A = 54m² = l*w

l = w + 3

54 = w (w+3)

54 = w² + 3w

w² + 3w - 54 = 0

w² + 9w - 6w - 54 = 0

w (w + 9) - 6 (w + 9) = 0

(w - 6) (w + 9) = 0

w - 6 = 0 = > w = 6 m

w + 9 = 0 = > w = - 9 < 0 (F)

l = w + 3

l = 9 m
