Question

the perimeter of a parallelogram is 160cm. if one of the sides is 20 cm longer than the other find the length of each of its sides​

Answer 1

Answer:

perimeter of a parallelogram is 2(length+ breadth)

let the length of parallelogram be X so the breadth of the parallelogram will be X+20

so we will get the equation from our 1st point

2(X+X+20)=160

so 2(2X+20)=160

taking 2 at the denominator of 160

so 2X+20=80

so 2X=80-20

so 2X=60

so X=30

so the length will be 30
