Question

ratio of adjacent side of parallelogram is 2:3. Find the length of each side if its peremeter is 80

Answer 1

Let the length and breadth be x.
perimeter of parallelogram = 2(l + b)
80 = 2(2x + 3x)
80 = 2(5x)
80 = 10x
x = 8
Therefore, Length = 3 * 8 = 24
and breadth = 2 * 8 = 16

Answer 2

let the constant of the ratio be x
as perimeter of parallelogram=2(l+b)
2(3x+2x)=80
2*5x=80
10x=80
x=80÷10
x=8

as x=8 thus lenght=3×8 and breadth=2×8

lenght=24  breadth=16
