Solve.If the three lengths of the sides of a triangle are known, Heron's formula can be used to find its area. If a, b, and c are the three lengths of the sides, Heron's formula for area is: A = 
where s is half the perimeter of the triangle, or s = 
(a + b + c).Use this formula to find the area of the triangle if a = 7 cm, b = 9 cm and c = 14 cm.
