Two of the sides of a right angled triangle are 5m nd 12m.find the length of the third side(there are two possible answers)

the 51213 right triangle is one of the most commonly used ones.
So, you have a 5m12m13m triangle.
Or, you may have one with sides
5m,√119 m,12m
but usually the hypotenuse is not called one of the "sides" in a right triangle.
