Answer:
area = w² + 8w
Step-by-step explanation:
the equation for calculating the area of something is:
area = length x width
length = 8 + width
area = (8 + width) x width
I will use w instead of width
area = w² + 8w
we can solve for w:
240 = w² + 8w
w² + 8w - 240 = 0
(w - 20) x (w + 12) = 0
so we know that the length of the pool is 20 feet and the width is 12 feet
