Assuming one leg is (a) and the hypotenuse is (c),the formula we will use for a right-angled triangle is:

where b is the length of the third side.

We plug the values into the equation,



The length of the third side is or b ~ 7.21 cm.

To show how you obtained the answer :

b =

We separate as ---> since 4 x 13 = 52.

We know that and cannot be simplified so we keep it and,

b = or b ~ 7.21cm.
