Answer:
Length = 15 and Width = 9
Step-by-step explanation:
5:3 = 135
make 5, 5x and 3, 3x so that would be 5x*3x = 135
when you times two x's that makes x²
making 15x² = 135
Divide 15 on both sides making 135 now 9
so x² = 9
with a squared x you used a square root
√9 = 3
so x is equal to 3
then put those into 5x, 5(3) and 3x, 3(3)
thus making 15 sq. ft and 9 sq. ft
