As you know from elementary geometry you can calculate the area of a triangle by oh where V is the length of the base and h is the length of the height of the triangle. If you do not know the height of the triangle and just know the lengths of the three sides you can use Heron's formula. Heron's formula states that given the lengths of the sides of the triangle (a, b, and c) we can calculate its arca by A = Vpp-a)p-6)(p-c) where p is the semi-perimeter of the triangle p = }(a+b+c). Note that to take a square root in Java use the command Math.sqrt(x). So the following command will store the square root of the value of the variablet into the variable root double root = Math. sqrt(1); You can put any valid expression inside the square root as well, so for example root = Math.sqrt(15.8t + 27.9/y + 4.2): is a valid assignment statement. B 1 0 Write a program that asks the user to input three integers as the side lengths of the triangle then outputs the area. You should try the following sample run. Input the length of side A: 4 Input the length of side B: 5 Input the length of side C: 7 The area is = 9.797958971132712
