उत्तर

Let `square`ABCD be a parallelogram.

AB : BC = 3 : 4

If AB = 3x cm

So, BC = 4x cm        ...(x is the common multiple.)

∴ CD = AB = 3x cm and AD = BC = 4x cm      ...(opposite sides of parallelogram)

Perimeter of `square`ABCD = 112 cm

∴ AB + BC + CD + AD = 112

∴ 3x + 4x + 3x + 4x = 112

∴ 14x = 112

∴ x = `112/14`

∴ x = 8

∴ CD = AB = 3x = 3 × 8 = 24 cm

∴ AD = BC = 4x = 4 × 8 = 32 cm
