How does PowerPoint know which objects to group? The objects are aligned side by side. The objects are placed in one part of the slide. The objects are selected using the Ctrl key. The objects are highlighted and dragged together.

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.
