Question

Complete the class ProcessRectangle given below.

1.Create a rectangle with a width of 60 and a height of 50 at x = 100, y = 200.
2.Call the translate method to move the rectangle 20 pixels in the x direction and 30 pixels in the y direction.
3.Print the new x and y in this format: x, y (Rectangle has methods to get x and y)
4.Call the grow method the rectangle to make the rectangle 10 units larger on both the left and right side leaving the height unchanged.
