One side of the rectangle is 15 m, the other side is 2.5 shorter than the first, calculate the perimeter of the rectangle

To find the perimeter of a rectangle, we will first of all recall the formula for finding the perimeter of a rectangle.

P = 2 (a + b);

The condition says that one side of the rectangle is 15 meters. It is also known that its second side is 2.5 meters shorter than the first one.

Let’s calculate the length of the second side of the rectangle:

15 – 2.5 = 12.5 meters.

It remains for us to substitute the values into the formula and calculate the perimeter:

P = 2 (15 + 12.5) = 2 * 27.5 = 55 meters perimeter of the rectangle.
