Question

The perimeter of a parallelogram is 22 cm .  If the longer side measures 6.5 cm what is the measure of the shorter side?

Answer 1

Let the shorter side be x

∴ Perimeter = x + 6.5 + 6.5 + x    [sum of all sides]

22 = 2 ( x + 6.5)

11 = x + 6.5

⇒ x = 11- 6.5 = 4.5 cm

∴ Shorter side = 4.5cm
