The perimeter of the rectangle is 36cm. the width of the rectangle is 1/9 of its perimeter. what is the width of the rectangle?

Let’s find the width. We know the perimeter is 36 centimeters, and the width is 1/9 of the perimeter. To find the width, we multiply the fraction by the perimeter value:

1/9 * 36 = 36 * 1: 9 = 36: 9 = 4 (centimeters) – width.

The rectangle has two widths and two lengths, if we subtract two widths from the perimeter, we get two lengths:

36 – 4 – 4 = 32 – 4 = 28 (centimeters) – two lengths.

To find one length, divide the previous result by 2:

28: 2 = 14 (centimeters).

Answer: the length is 14 centimeters.
