If side A is 3m and side B is 4m, what would be the length of the remaining side C?

If side A is 3m and side B is 4m, what would be the length of the remaining side C?
A = 3m ; B = 4m ; C =?Use Pythagoras Theorem to give the equation: A2 + B2 = C2 Rearrange:(A2 + B2)1/2 = C
Because I do not have a square root command on this window I have used the 1/2 as seen above, it mathematically correct but may not be the way your normal see this equation. Sub in values for A and B:
(32 + 42)1/2 = C (9 + 16)1/2 = C 251/2 = C 5 = C
Therefore the final answer is: 5m = C
