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
