# Perimeter of a pa

AB = DC =18 m

Perimeter of parallelogram ABCD = AB + BC + CD + DA

96 = 18 + BC + 18 + BC

(opposite sides of a parallelogram are equal)

2 BC = 96 – 36 = 60

BC = AD = 30 m

Given, area of parallelogram ABCD = 270 m2 We know that,

Area of a parallelogram = b × h (corresponding height)

Taking AB as the base,

AB × l = 270

18 × l = 270

l = 15 m

30 × m = 270

m = 9 m

Length of the other side = 30 m

Length of altitude l = 15 m

Length of altitude m = 9 m
