Example 5
Find the perimeter and area of the parallelogram PQRS given below :
Solution:
Perimeter = 2 ( 3.5 + 4 )
= 15 cm
Area = 4 ´ 3
= 12 cm
Example 6
Find the perimeter and area of DABC & D LMN
Solution:
Perimeter D ABC = 3 + 4 + 5 = 12 cm
Area of D ABC = 
´ 4 ´
3 = 6 cm2
Perimeter D LMN = 36 + 36 + 52 = 124 ft.
Area of D LMN = ´ 52 ´ 25 = 650 sq.ft.
