The length of a rectangular swimming pool is 7 yards greater than the width. If the area of the pool is 60 square feet, what is the length of the swimming pool?

Answer: 23.548 feet

Step-by-step explanation:

Area = 60 square feet

Width = y

Length = y + 7yards

Note:

1 yard = 3 feet

7 yards = 21 feet

Area of rectangle = width * length

60 = y * (y + 21)

60 = y^2 + 21y

y^2 + 21y - 60

using the quadratic formula calculator, and choosing the positive output.

y = 2.548 feet

Therefore, width (y) = 2.548 feet

Length = (width + 21 feet)

Length = 2.548 feet + 21 feet

Length = 23.548 feet
