Question

the perimeter of a parallelogram is180 CM one of its sides is greater than the other by 30 CM find the length of the sides of the parallelogram ​

Answer 1

Step-by-step explanation:

Let the two sides of a parallelogram be....

a = x cm and b = x + 30 cm

perimeter = 180cm

2 ( a + b ) = 180

= 2 ( x + x + 30 ) = 180

2 ( 2x + 30 ) = 180

2x + 30 = 180/2

2x + 30 = 90

2x = 90 - 30

2x = 60

x = 60/2

x = 30

the length of sides of paralleleogram

x = 30 cm and

x + 30 = 30 + 30 = 60 cm
