Question

the ratio of the two sides of a parallelogram is 1:2 and its perimeter is 60cm . find the sides of the parallelogram

Answer 1

Given :- two sides of parallelogram are in the ratio 1:2
Perimeter = 60cm

Let one side be 1x cm
another side = 2x cm

Perimeter = 60
➡2(length + breadth) = 60
➡2(2x+1x) = 60
➡2(3x) = 60
➡3x = 60/2
➡3x = 30
➡x = 30/3
➡X = 10

one side = 1x = 1*10 = 10cm
another side = 2x =2*10 = 20cm
