 Example: The sides of a quadrilateral ABCD are 5 cm, 6 cm, 9 cm and 8 cm. Find its perimeter. Solution: Perimeter of the Quadrilateral (P) = S1 + S2 + S3 + S4 Where P is the perimeter of the quadrilateral and S1, S2, S3 and S4 are the sides of the quadrilateral. Given that, S1 = 5 cm, S2 = 6 cm, S3 = 9 cm and S4 = 8 cm. Hence P = 5 + 6 + 9 + 8 P = 28 cm. Directions: Read the above example carefully and answer the following questions. Also draw 10 different quadrilaterals and find their perimeters.
