Question

Two sides of a parallelogram are in the ratio. 3 : 5. Find the length of sides if the perimeter is 32 cm.
​

Answer 1

Answer:

let two opposite sides be 3x and 5x

perimeter of the parallelogram=2(length+ breadth)

2(3x+5x)=32

8x=16

x=2

so sides will be 6,10,6,10

Answer 2

Answer:

Perimeter of parallelogram = 2(length+breadth)

let the length= 3x

let the breadth= 5x

perimeter= 2(l+b)

32 =2(3x+5x)

32 =2×8x

32÷2=8x

16=8x

x=16÷8

x=2

length= 3×2=6

breadth=5×2=10
