Question

3. Two sides of a parallelogram are in the ratio 4:3. If its perimeter is 56 cm, find the lengths
of its sides
​

Answer 1

Answer:

let the sides be 4x & 3x

now, we know that,

perimeter of a parallelogram = 2 (a+b)

56 = 2 (4x+3x)

28 = 7x

4 = x

therefore, one side will be 4x =4 (4) =16cm

and the other one will be 3x = 3 (4) = 12cm

Answer 2

permeter of pallelogram = 2(a+b) = 56

2( 4x+3 x ) = 56

2( 7x)= 56

14x = 56

x= 4

the side's

4x= 4×4 = 16cm

3x = 3×4 =12 cm
