| It is known that we are given a rectangular shape. So, let’s determine what the perimeter of a rectangular figure is equal to.

The perimeter of a rectangular shape is the sum of the lengths of all sides of the shape. A rectangle has 2 pairs of sides, in which the sides are equal and parallel to each other.

It is known that the first side of the rectangle is 9 cm, and the second is 5 cm less. Means:

The length of the second side of the rectangle = the length of the first side – 5 cm = 9 cm – 5 cm = 4 cm.

Find the perimeter:

Perimeter = first side * 2 + second side * 2 = 8 + 18 = 26 cm.

Answer: 26 cm.
