A(w) = 40w - w^2

Step-by-step explanation:

Given

P = 80 --- perimeter

Required

Define the area in terms of width

The perimeter of the pool is:

P =2(l + w)

Where:

$l\to length$

$w\to width$

So:

80 =2(l + w)

Divide by 2

40 =l + w

Make l the subject

l = 40-w

The area is then calculated as;

A(w) = l * w

Substitute: l = 40-w

A(w) = (40 - w) * w

A(w) = 40w - w^2
