Given that 3cm and 4cm are the shorter sides of a right-angled triangle, find the length of the hypotenuse.

When given 2 known sides of a right angled triangle, we can use Pythagoras' Theorem to find the last unknown side. The formula follows as below:A² = B² + C²Where A represents the longest side of the triangle (the hyoptenuse) and B & C are the other 2 sides (does not matter which of the 2 sides are assigned to B or C). Substituting in 3cm and 4cm into B and C and then taking the sqaure root will give us our value for A which is 5 cm.A = Sqrt(9 + 16) = 5cm
