Question

the ratio of two adjacent sides of a parallelogram is 3:1 and its perimeter is 72cm.what is the length of the adjacent sides?​

Answer 1

let one side of parallelogram = x.

another side of parallelogram = 3x

given perimeter = 72cm

opposite sides of parallelogram are equal..

solve. .

x+3x+x+3x = 72

8x =72

x = 72/8

x = 9

other side = 3 * 9 = 27

so the sides are 9cm , 27cm

hence solved..

Answer 2

Answer:

27

Step-by-step explanation:

Let one side of parallelogram be -x

another side= 3x

given,

perimeter=72 cm

opposite sides are equal of a parallelogram

A/Q=`

x+3x+x+3x=72

8x=72

x=72/8

x=9

one side=9

another side=3×9=27
