The width of the rectangle is 5 times less than its length, and the area is 720 cm2.

The width of the rectangle is 5 times less than its length, and the area is 720 cm2. Find the width and length of this rectangle.

The area of a rectangle is the product of its width and length.

We draw up an equation in which we write the width as a cm.

We know that the length is 5 times longer, so it will be: 5 * a.

Thus, we get:

a * 5 * a = 720.

5 * a ^ 2 = 720.

a ^ 2 = 720/5 = 144.

a = 12 cm (rectangle width).

5 * a = 5 * 12 = 60 cm (rectangle length).

Checking the solution:

12 * 60 = 720 cm2

Answer:

Length 60 cm, width 12 cm.
