MIPS Assembly Language

Do all calculations using double precision floating point representation. This means that you must do the input and output as type double.

Use functions for all calculations. This means that you need a function to calculate the length of the x and y lines, the square of the length of the line between the points and the area of the circle, square and rectangle (5 functions). I did some of this as an example, so I am giving you this code. You do not need to write functions to do the input or output if you dont want to. The circle, square and rectangle functions should output the results.

Do not use the menu from lab 3. Instead, write a main program that consists of getting the four input values, calls the circle function and returns, calls the square function and returns, calls the rectangle function and returns and terminates. The circle, square and rectangle functions will need to call the other functions in order to do their job. Therefore, you will have nested function calls. You will need save some of the return addresses in places other than register $ra. You can do this with the jalr instruction or by using the stack.

Test the program using the following data:

x1: 1, y1: 1, x2: 2, y2: 2 Circle Area: 6.2382 Square Area: 2.0 Rectangle Area: 1.0

x1: 3, y1: 5, x2: 7, y2: 9 Circle Area 100.5312 Square Area: 32.0 Rectangle Area: 16.0

This is what i have
