Answer:
Step-by-step explanation:let one side of triangle =x
so the another two sides = x+1 and x+2
perimeter of a triangle =sum of all sides
perimeter =72cm
72cm=x+x+1+x+2
72cm=3x+3
72-3=3x
69=3x
x=69/3
x=23
one side of triangle =23cm
second side of the triangle =23+1=24cm
third side of the triangle =23+2=25cm
That is your answer
