Question

the ratio of two sides of a parallelogram is 3:5 if the perimeter is 64cm find the lenght of a sides of the parallogram​

Answer 1

Answer:

Let one side be 5x and another side is 3x so opposite sides must be 5x and 3x because it's a parallelogram and thus opposite sides are same

Perimeter = sum of all side

64=5x+3x+5x+3x

64=16x

x=4

So sides of parallelogram are 20,12,20,12.

Answer 2

Answer:

ratio: 3x,5x ( let)

perimetre: 64cm

so, perimetre: 2(l+b)

64cm= 2(5x+3x)

64cm= 2(8x)

64cm=16x

64/16=x

4=x

length = 5x=5×4=20cm

breadth =3x=3×4=12cm

sides are = 20cm,12cm,20cm,12cm
