The hypotenuse of the smaller triangle is 5.\r

\n" ); document.write( "\n" ); document.write( "To find the hypotenuse of the larger triangle, note that the areas are in the ratio 4:5, with 4 corresponding to the smaller triangle. This is a two dimensional specification, so if we take the square root we will obtain the ratio of side lengths (one dimensional).\r
