Solution:
Given, the figure is a parallelogram LMNO
We have to find the perimeter of the parallelogram.
We know that, the perimeter of parallelogram = 2(LM + MN)
From the figure,
LM = 22 cm
MN = 18 cm
So, perimeter = 2(22 + 18)
= 2(40)
= 80 cm
Therefore, the perimeter of the parallelogram is 80 cm.
Summary:
The perimeter of parallelogram LMNO is 80 cm.
