Finding missing side -parallelogram

Ans: Height of the parallelogram = 45 cm Example 1: Find the height of a parallelogram whose area is 540cm2and base is 12 cm. Solution: Given: Area(A) = 540 cm2 Base(b) = 12 cm To find: Height(h) Area of a parallelogram = b x h sq units 540 cm2 = 12 x h 12 x h = 540 cm2 (transposing 12 to RHS) h = 270 h = Divide 540 and 12 with 2 6 135 h = Divide 270 and 6 with 2 3 h = Ans: Height of the parallelogram = 45 cm

Given: Area(A) = 63m2 , Height(h) = 9m To find: Base(b) Example 2: The area of the parallelogram is 63m2. Find the base if its height is 9m. Solution: Given: Area(A) = 63m2 , Height(h) = 9m To find: Base(b) Area of a parallelogram = b x h sq units 63m2 = b x 9 b x 9 = 63m2 (transposing 9 to RHS) b = b = 7 Ans: Base of a parallelogram = 7 m

Try These 1. The area of parallelogram is 70 cm2. Find height if base is 5 cm. 2. Find the base of a parallelogram whose area = 480 m2 and height = 30m
