Hi Kasey,

The hypotenuse is the side of a right triangle that is opposite the right angle. The other two sides are sometimes called legs.

The theorem of Pythagoras states that is the legs of a right triangle have lengths a and b and the hypotenuse has length c then a² + b² = c², in other words a squared plus b squared equals c squared.

It looks to me that you have a right triangle with legs of length 96 and 108 units. If this is the case the hypotenuse has length c where

96² + 108² = c²

thus

c² = 9216 + 11664 = 20880

and hence

c = √20880 = 144.499 units
