The perimeter of a parallelogram is 24 cm. What is the sum of 2 adjacent sides?

From the condition it is known that the perimeter of the parallelogram is 24 cm. You need to find what the sum of 2 adjacent sides of the parallelogram is equal to.

We’ll start by remembering what a perimeter is and how you can find it for a parallelogram.

So, the perimeter of any geometric figure is equal to the sum of the lengths of all sides of this geometric figure.

A parallelogram has equal opposite sides, so the formula for finding the perimeter looks like this:

P = 2 (a + b).

To find the sum of two adjacent sides, you need:

a + b = P / 2.

We calculate:

a + b = 24/2 = 12 cm.
