Question

the length of the rectangle is 3 less than twice the width. If the area is 9 square ft, the length and width of the rectangle​

Answer 1

Answer:

w = 3ft

l = 3ft

Step-by-step explanation:

 l = 2w - 3

9 = l x w

substitute

9 = (2w - 3)w

0 = 2w^2 - 3w - 9

the values of w will be 3 and -3/2 ; neglect -3/2 because there is no negative measurement

w = 3ft ; l = 2(3) - 3

l = 3ft
