If AB and CD are two parallel sides of a parallelogram, then:

• AB>CD

• AB<CD

• AB=CD

• None Of Above

The perimeter of a parallelogram whose parallel sides have lengths equal to 12 cm and 7 cm is

• 21 CM

• 42 CM

• 19 CM

• 38 CM

Answer explanation

Explanation: Perimeter of parallelogram = 2 (Sum of Parallel sides)

P = 2 (12 + 7)

P = 2 (19)

P = 38 cm
