Chapter 7, Problem 76(choose chapter or problem)
If the three lengths of the sides of a triangle are known, Heronsformula can be used to find its area. If a, b, and c are the lengths ofthe three sides, Herons formula for area isA = 2s1s - a21s - b21s - c2where s is half the perimeter of the triangle, or s = 121a + b + c2.Use this formula to find the area of each triangle. Give an exactanswer and then a two-decimal-place approximation. cm3 cm2
