Question

2 adjacent sides of paralleogram are in the ratio 3:2 the perimeter of parallelogram is 72cm.find the length of each of its sides

Answer 1

perimeter of paralleogram is 2(l+b)

two sides are given a 3:2

let x for the sides

then the sides are 3x and 2x respectively

then according to the formula

2(l+b)=72

2(3x+2x)=72

6x+4x=72

10x=72

x=7.2

therefore 2 sides are= 3*7.2=21.6

2*7.2=14.4

hope it helps

Answer 2

Answer:

The sides of parallelogram are 21.6 and 14.4.

Step-by-step explanation:

Let the common factor be x

Therefore the l = 3x and the b = 2x

Perimeter of parallelogram = 2 ( l + b )

                                           72 = 2 ( 3x + 2x )

                                            72 = 2 x 5x

                                            72 = 10x

                                             x = 7.2

Therefore l = 3x

                 l = 3 x 7.2

                l = 21.6

and b = 2x

        b = 2 x 7.2

        b = 14.4

The sides of parallelogram are 21.6 and 14.4.
