Answer 2

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
