Question

the adjacent sides of a parallelogram are in the ratio 1:2. if the shorter side is 12cm .find the perimeter.​

Answer 1

Answer:

72cm

Step-by-step explanation:

the ratio is1:2

1=12cm so,

2=12×2

2=24cm

in parallelogram opposite sides are equal

the perimeter is 12+24+12+24

=72cm

Answer 2

Shorter side=x=12

Longer side=2x=24

Perimeter =2(l+b)=2(2x+x)=2(3x)

=2(12+24)

=72
