Grade 7 - Mathematics
9.18 Perimeter of a Quadrilateral

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.
