Example:
The parallel sides of a parallelogram ABCD are 5 cm and 7 cm. Find its perimeter.

Solution: Perimeter of the Parallelogram (P) = 2 [b + a]
Where P is perimeter of the parallelogram, a and b are parallel sides.
Given that,
b = 5 cm and a = 7 cm.
P = 2 [b + a]
P = 2 [5 + 7]
P = 2 [12]
P = 24 cm.

Directions: Read the above example carefully and answer the following questions. Also draw 10 different parallelograms and find their perimeters.
