Write a function that will calculate the perimeter (sum of all sides) of a right triangle. The function will take two real number parameters for the two sides of the right triangle. The function will return the result it computes and be sure to show the header. Add for full credit a call expression to the function from main. Assume appropriate libraries have been called. VI. Write the full program which Uses the well known trapezoidal rule(The function to do this follows) to get an accurate area under the curve for the mathematical function u(t)=5t (sin3t + 8): from 0 to 0 9 radians. The function (u(t) should be gotten via a separate call to a C++ function. To further clarify, you are to write the full program and also the u(t) C++ function. double integrate (double a, double b, int n) {//Declare objects local variables for this function double sum(0), x, base, area; base = (b - a); for (int k=2; k
