The length of each of its parallel side are 30 cm and 40 cm.

Step-by-step explanation:

  • Perimeter of parallelogram = 140 cm.
  • The one side of parallelogram = x cm.
  • The other side of parallelogram = x+10 cm.

Perimeter of a parallelogram = 2 (base+height)

⇒ 140 = 2(x+x+10)

⇒ 140 = 2(2x+10)

⇒ 140 = 4x+20

⇒ 4x = 120

⇒ x = 120/4

x = 30 cm

∴ The longer side = 30+10 = 40 cm
