mark me the brainiest!

The length is 15 ft
The width is 12 ft
Step-by-step explanation:
we know that
The area of rectangle is equal to
A
= LW
we have
A = 180 f12
SO
180 = LW
> equation A
W=L-3
-> equation B
substitute equation B in equation A and solve for
I
180 = L(L-3)
180 = 1? - 3L
1'-3L-180=0
using a graphing tool-----> solve the quadratic
equation
The solution is L= 15 ft
see the attached figure
Find the value of W
W=15-3=12 ft
