Answer 2

let ABCD be the parallelogram.

then, let AB = 3x and BC =4x

CD = AB = 3x (opposite sides of parallelogram are equal)

AD = BC = 4x (opposite sides of parallelogram are equal)

Perimeter = 84 cm

AB + BC + CD + AD =84cm

3x + 4x + 3x + 4x = 84cm

14x = 84cm

x = 84/14

x = 6cm

AB = CD = 3x = 3×6 = 18cm

BC = AD = 4x = 4×6 = 24cm
