Write a program that inputs the sizes of a geometric figure and calculates its area. The figures are four types: square, rectangle, circle and triangle.
The first line of the input reads the type of the figure (
- If the figure is a square, the next row reads one number - the length of its side.
- If the figure is a rectangle, on the next two rows we read two numbers - the lengths of its sides.
- If the figure is a circle, the next row reads one number - the radius of the circle.
- If the figure is a triangle, on the next two rows we read two numbers - the length of the side and the length of its height.
Round the result up to the third digit after the decimal point.
