The pool is rectangular in shape, the length of which is 1.8 times the width.

The pool is rectangular in shape, the length of which is 1.8 times the width. The pool area is 4500 m2. Find its length.

1. Let the width of the pool be x meters.

Let’s find the length of the pool.

1.8 * x = 1.8 x meters width of the pool.

2. Find the area of the pool for this pool length multiply by its width.

x * 1.8x = (1.8×2) m2 area of the pool, and according to the condition of the problem 4500 m2.

3. Let’s compose and solve the equation.

1.8×2 = 4500;

x2 = 4500 / 1.8;

x2 = 2500;

x = 50.

4. The width of the pool is 50 meters.

5. Find the length of the pool 1.8 * 50 = 90 meters.

Answer: 90 meters.
