3. Find the area of a triangle whose sides are 34 cm, 20 cm and 42 cm. hence, find the length of the altitude corresponding to the shortest side. Solution: Consider 34 cm, 20 cm and 42 cm as the sides of triangle a = 34 cm, b = 20 cm and c = 42 cm We know that S = Semi perimeter = (a + b + c)/ 2 Substituting the values = (34 + 20 + 42)/ 2 = 96/2

In this paper a rational triangle means a triangle in the plane whose sides are of rational length. We consider the set of such triangles with a given area A(neces-sarily the square root of a positive rational number). We show there are in nitely many rational triangles for each such area A(Theorem 1). This was previously
