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.

L=15 W=12 15*12 = 180

Step-by-step 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
