One side of the rectangle is 24 centimeters and the other is 3 times larger Find the perimeter of the rectangle.

The perimeter of a rectangle is the sum of the lengths of all its sides.
Formula for finding the perimeter of a rectangle:
P = 2 (a + b), where P is the perimeter of the rectangle, a is the width of the rectangle, b is the length of the rectangle.
Semi-perimeter is the sum of the length and width of a rectangle.
To get the perimeter from the semi-perimeter of a rectangle, you need to double the semi-perimeter.
The task is solved in 2 steps:
In the first, we find the other side of the rectangle (length):
1) 24 * 3 = 72 (cm) – the length of the rectangle.
In the second step, we find the perimeter of the rectangle using the formula:
2) 2 (24 + 72) = 192 (cm) – the perimeter of the rectangle.
Answer: 192 cm.
