One side of the rectangle is 24 cm and the other is 3 times larger. What is the perimeter of the rectangle?

We are given a rectangle, one side of which is 24 centimeters, and the other side is three times larger than this side, we need to find the perimeter of this rectangle, let’s start solving:

First, let’s find this side, it will be equal to 24 * 3 = 72 (centimeters). This side will be the length, since it is always larger than the width in the rectangle.

Since the length and width in the rectangle are equal to each other, and the perimeter of the rectangle is equal to the sum of all its sides, denoting the length with the letter a, and the width with the letter b, the equality will be true that:

P = (a + b) * 2, then substituting the values ​​we find the perimeter:

P = (24 + 72) * 2;

P = 96 * 2

P = 192 (centimeters)

Answer: the perimeter is 192 centimeters
