Question

understanding quadrilaterals

Answer 1

let one side be x
so other side be 2x
peri of parallelogram is 2(l+b)
2*(x +2x) =120
2x+4x=120
x=120/6
x=20
2x=40

Answer 2

let one side be x

Therefore, other side be 2x

perimeter of parallelogram =2(l+b)

2*(x +2x) =120

2x+4x=120

x=120/6

x=20

2x=40
