Description

There is a known sort of point definition. Define a rectangular class, as described below: Contains four properties: lower left corner, top right corner two points, area, perimeter. Area, the perimeter is determined by the lower left corner, two points in the upper right corner; the member function has (1) a constructor and a copy constructor (2) calculates the area of the rectangle (3) calculates the perimeter

Input

There are multiple sets of data. Each set of data contains four data x1,y1,x2,y2, representing the lower-left corner of the rectangle and the horizontal ordinate of the upper-right corner, respectively.

Output

Area and perimeter of a rectangle

Sample Input

-1-1 2 3 -5-6 0-1

Sample Output

12 14 25 20
