Grade 7 - Mathematics9.16 Perimeter of the Parallelogram

 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.
