A rectangular swimming pool has a perimeter of 96 ft. The area of the pool is 504 ft2. Which system of equations models this situation correctly?
The answer is
48 = l + w
504 = l w
l - the length of the pool
w - the width of the pool
The perimeter P of the pool is:
P = 2(l + w)
P = 96 ft
96 = 2(l + w)
96/2 = l + w
48 = l + w
The area A of the pool is
A = l w
504 ft² = l * w
