1212Write a c++ code that will calculate the roots of a quadratic equation a2+ bx+c=0 Hint: d = sqrt (b2-4ac), and the roots are: x1 = (€“b + d)/2a and x2 = (€“b €“ d)/2a (use sqrt function from cmath.h )?

944Problem 5: Hero's Formula is A method for calculating the area of a triangle when you know the lengths of all three sides. Let a, b, c be the lengths of the sides of a triangle. The area is given by:A= pp-ap-b(p-c) | wherep= a+b+c2 | | Write a C-language code to calculate area of triangle using above method. Take the three lengths of the triangle from the user and display the area that your program calculates.
