	My little computer here tells me that sides of 3/2 and 20/3 give an area of 5 and a hypotenuse of 41/6. Scanning the output, there seem to be no more answers where the fractions are reduced to simplest terms, and all the numerators and denominators are less than 100. ( I was expecting some obscure answer with multi-digit denominators.) -Jim Grant, Littleton
