Question

The ratio of a parallelogram is 2 : 3 and its perimeter is 30 cm, find the measure of the side.​

Answer 1

Answer:

Given:The ratio of adjacent sides of a parallelogram is 2:3

Let the lengths of the adjacet side be 2x and 3x respectively.

Also,perimeter=30cm

⇒2(2x+3x)=30cm

⇒10x=30cm

⇒x= 30/10

x=3cm

Thus, the adjacent sides of parallelogram are 6cm and 9cm

Hence area=6×9=54 sq cm
