Question

if the adjacent sides of a parallelogram are in the ratio 2:3 and the sum of all the sides is 50 cm, find the sides of the parallelogram

Answer 1

Let the lengths of the sides be x and y respectively. Then;

`(x)/(y) = (2)/(3)`
x=
`(2)/(3) y`
We also know that x+y=50
Replacing value of x;

`image`
`2y+3y=150`
5y=150
y=30
x=
`(2)/(3) *30`
x=20
The length of the sides of parallelogram are 20cm and 30 cm.
