The diagonal of a rectangle forms a right triangle with the length and width.
a=length=12in; b=width=7in; c=diagonal
a%5E2%2Bb%5E2=c%5E2
%2812in%29%5E2%2B%287in%29%5E2=c%5E2
144in%5E2%2B49in%5E2=c%5E2
193in%5E2=c%5E2 Find the square root of each side.
13.89in=c ANSWER: The diagonal is 13.89 inches.
