| The length of a rectangular pool is 5 times its width, and the width is 200m less than its length. Find the area of the pool.
1. If we take the width of the pool as x cm.
2. Then, knowing that its length is 5 times greater than its width, we will take the length as 5 * x cm.
3. And since from the condition of the problem we know that the width of this basin is 200 m less than its length, so we can draw up an equation, solving which we will calculate what its width is equal to.
5x – x = 200;
4x = 200;
x = 200/4;
x = 50 m.
4. Now let’s define what the length of the pool is.
50 * 5 = 250 m.
5. Knowing the measurements of the pool, we calculate what its area is equal to.
50 * 250 = 12,500 m ^ 2.
