Question

The perimeter of a parallelogram is 102 cm. if one side is greater than the other by 9 cm, find the length of all the side

Answer 1

perimeter of a parallelogram is sum of all sides or 2( l + b )

length = x

breadth = x + 9

perimeter = 102cm

2 ( l + b ) = 102

2 ( l + b ) = 102

2x + 9 = 102 / 2

2x + 9 = 51

2x = 51 - 9

2x = 42

x = 21 cm

x + 9 = 30 cm
