Write a function float computearea(int *v1, int *v2, int shape )that computes the area of fourbasicgeometric entities. the geometric entity will be identified by the argument shape which is 1 for triangle, 2 for square/rectangleand 3 for circle. the arguments v1 and v2 are pointers to the two arguments defining the shape. for circle v1 is a pointer to the diameter of the circle, v2 is null, for rectangle/square, v1 and v2 are pointers to the height and width for triangle v1 is a pointer to the the base and v2 points to the height of the triangle.
