Question

the ratio of two adjacent sides of a parallelogram is 2:3 its perimeter is 50cm.

Answer 1

let the sides be 2x and 3x
since opposites sides in parallelogram are equal then all sides are 2x ,2x,3x,3x
perimeter =2 (l+b)
50cm=2 (2x+3x)
50/2= 5x
25=5x
x= 25/5
x=5
solution: sides are 10 cm, 15 cm, 10 cm, 15 cm
hope it helps

Answer 2

Let sides be 2x & 3x

as we know that

perimeter of parallelogram = 2 ( sum of adjacent sides )

50 = 2 (2x + 3x)

50 = 2 × 5x

50 = 10x

x = 5

so sides are 10 cm & 15 cm
