Answer:
As others have already said a 3, 4, 5 triangle is the solution.
To solve the problem as stated:
1. Length of one side is x cm.
2. Length of other side is (x+1) cm
3. Hypotenuse is given as 5 cm
In a right triangle: c^2=a^2+b^2
Substituting our values for a, b and c: 5^2=x^2+(x=1)^2
or simplifying the above equation: x^2+x-12=0
Solving this (quadratic) equation you get x=6/2 or -8/2
so side a=3 and side b=4
