Step-by-step explanation:
let, the breadth be = x
let the length be = x + 30
the perimetre = 180
=)2 ( x + x+ 30 ) = 180
=) 2x + 2x+ 60 = 180
=) 4x = 180 - 60
=) 4x = 120
=) x = 120 / 4 = 30 .
So, the lenght is = length = 30 + 30 = 60.
= breadth = 30. Parallelogram has two parrellel sides so , the lenght of it's all sides are - : 60,60,30,30.
