Heron's formula gives a method of finding the area of a triangle if the lengths of its sides are known. Suppose that a, b, and c are the 1 (a +b+c). Then the 2 lengths of the sides. Let s denote one-half of the perimeter of the triangle (called the semiperimeter), that is, s = area of the triangle is A = Vs(s- a)(s - b)(s – c). Find the area of an island in the form of a triangle if the sides of this triangle measure approximately 15 mi, 7 mi, and 9 mi. The area of the triangle is approximately (Do not round until the final answer. Then round to one decimal place as needed.)
