Re: Rectangles and Squares

The area of the rectangle is 3*4, not 2(3+4) - this is its perimeter.
As it seems, the right answer is 62cm^2, not 140cm^2.

The answer is 140 cm^2.[color=beige] . [/color][color=blue]How did they get this?[/color]

Code:
              4
          *-------*
          |       |
         4|  16   |4
          |       |
      *---*-------*---*
     3| 9 |  12   | 9 |3
      *---*-------*---*
          |       |
         4|  16   |4
          |       |
          *-------*
              4
