Answer:
Width = 12
Length = 15
Step-by-step explanation:
Area = length * width
180= w*(w+3)
180= w^2 + 3w
0= w^2 + 3w -180
Use the quadratic to solve for w
w= 12 , w=-15
Negative lengths don't make sense so 12 = w
l=w+3
l=12+3
l=15
Answer:
Length is 15
Width is 12
Step-by-step explanation:
l=3+w
A=180
180=(3+w)w
180=w^2+3w
0=w^2+3w-180
w=12 or -15
w can not be negative so it equals 12.
l=12+3
l=15
