Question

the perimeter of a parallelogram is 100 cm and one of its adjacent sides is longer than other by 10 cm find the length of its sides ​

Answer 1

Answer:

20

Step-by-step explanation:

perimeter of ll gram=2(l+b)

=2(x+(x+10))

=2(2x+10)

=4x+20

given that perimeter =100cm

therfore 4x+20=100

4x=100-20

x=80/4

x=20
