Question

the ratio of two sides of parallelogram is 3:4. if its perimeter is 56 cm. find the sides of parallelogram.

Answer 1

Let the length and breadth of the parallelogram be l and b respectively.

l= 3x
b = 4x

Perimeter of the parallelogram = 2(l + b)

56 = 2(3x + 4x)

7x = 28

x = 4

Hence,

Length = 3(4) = 12 cm.

Breadth = 4(4) = 16 cm.

Answer 2

perimeter- 56 cm
sides be - length ( l ). & breadth (b)
l = 3x & b = 4x
then perimeter- 2(l+b)
56= 2(3x +4x)
56/2= 7x
28 = 7x
4 = x
then , sides .- 3x = 3× 4=12
4x= 4×4=16
sides will be - 12,12,16,&16..
