Question

the perimeter of a parallelogram is 180 centimetre one of its side is greater than the other by 30 cm find the length of the side of a parallelogram​

Answer 1

Answer:

parimeter of the parllelogram = 180cm

let first side = x

then,

other side will be= x + 30

A. T. Q

2(l+ b) =180

2( x + x +30) = 180

2 ( 2x +30) =180

4x + 60=180

4x =180-60

4x = 120

x =120÷4

x = 30

Hence it's smaller side is 30

and largar side will be 30+ 30=60
