Question

The length of a rectangle is 3 cm greater than its width. the area of the rectangle is 180 cm². find the length and the width.

Answer 1

L=15 W=12 15*12 = 180

Explanation:

W*L = area

W*(W+3) = 180

Do the distributive

W^+3 W-180=0

Find 2 numbers that when multiplied ,the result is -180

and when added the result is 3

- 12* 15 = -180

-12 +15 = 3
