The perimeter of the parallelogram is 50 one of the sides 12. Find the length of the side adjacent to the given one.

In a parallelogram, opposite sides are equal.

This means two sides of 12 cm.

12 * 2 = 24 cm.

Let’s find the sum of the remaining two sides.

50 – 24 = 26cm.

And since these are opposite sides and they are equal.

So 26: 2 = 13 cm is the length of the adjacent side.

Answer: 13 cm.
