let the length of equal side be x
perimeter of a triangle is => sum of all sides
according to question ,
x+x+72 = 252
2x = 252-72 => 180
x = 180/2 => 90 cm
hope this helps

90 cm is the length. just subtract 72 from 252 .you will get 180 as the length of both the side is same divide it by 2 and you will get the answer 90
