1.

the perimeter of a parallelogram is 160 cm. if one of its sides is longer than the other by 10 cm, find the length of each of its sides.​

Answer»

Step-by-step explanation:

  • perimeter of a PARALLELOGRAM is 2(LENGTH+ breadth)
  • let the length of parallelogram be X so the breadth of the parallelogram will be X+10
  • so we will GET the EQUATION from our 1ST point
  • 2(X+X+10)=160
  • so 2(2X+10)=160
  • taking 2 at the denominator of 160
  • so 2X+10=80
  • so 2X=80-10
  • so 2X=70
  • so X=35
  • so the length will be 35 and the breadth Will be 45
