Problem 2: Calculating area of a triangle from the given vertices Consider a triangle with the following vertices: A(1, 31). B(x2, y2), and C(x3, Y3). The area of a triangle for the given vertices can be calculated using the following equation: ==—=|T1(Y2 − Y3) + £2(Y3 − Y₁) +£3(Y1 − Y2)| Area = a. Write a void function that accepts the vertices of triangle, calculates the area of that triangle using the above equation and prints the result at the console (without returning anything). b. Write a similar function like (a), but instead of printing the area of a traingle from within the function it returns the value of the calculated area. c. Write a program to calculate the area of a triangle with the following vertices: A(-1,2), B(2, 3), C(4, -3). Use both functions defined in (a) and (b). Make sure, the calculated area from function (b) should be displayed at the console also.

A spontaneous exothermic reaction at a constant temperature and pressure of 50∘C and 2.0 atm has an enthalpy decrease of 350 kJ. This reaction performs 150 kJ of useful work, which is 54% of the maximum work that could be done. What is the reaction’s change of entropy? Express your answer to two significant figures and include the appropriate units.
