Grade 7 - Mathematics 9.17 Perimeter of the Trapezoid
The sides of a Trapezoid ABCD are 15 cm, 9 cm, 12 cm and 8 cm. Find its perimeter.
Solution: Perimeter of the Trapezoid (P) = S1 + S2 + S3 + S4
Where P is the perimeter of the Trapezoid and S1, S2, S3 and S4 are the sides of the trapezoid.
S1 = 15 cm, S2 = 9 cm, S3 = 12 cm and S4 = 8 cm
P = 15 + 9 + 12 + 8
P = 44 cm.
Directions: Read the above example carefully and answer the following questions. Also draw 10 different trapezoids and find their perimeters.
