c) the area of the trapezium which has A and B by base, and C by height.

d) the area of the square that has side B.

e) the area of the rectangle that has sides A and B.

The input file contains three double values with one digit after the decimal point.

The output file must contain 5 lines of data. Each line corresponds to one of the areas described above, always with a corresponding message (in Portuguese) and one space between the two points and the value. The value calculated must be presented with 3 digits after the decimal point.
