Question

The area of a parallelogram is 12 1/4 cm square.if it's height is 1 6/7 cm ,find it's base.

Answer 1

area of parallelogram = height × base
given,
area = 12 1/4 = 49/4 cm²

height = 1 6/7 = 13/7 cm

then,

49/4 = 13/7 × base

base = 49× 7/13 × 4 = 343/52 cm
= 6.596 cm

Answer 2

Given,

Area of parallelogram = 12 1/4

= 49/4 cm²

Height = 1 6/7

= 13/7 cm

Area = Height * Base

49/4 = 13/7 * Base

Base = 7 * 49/13 * 4

= 343/52

= 6.59 cm Ans.
