The length of a pool is 10 meters more than twice the width. The area of the pool is 1500 square meters. What is the length of the pool?

Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w (2w + 10) = 1500.

Simplify.

2w squared + 10w = 1500

Make it a quadratic equation, w = 25 or - 30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60

Width = 25

Length is 1010, width is 494.
