Pseudocode and Equations

    # following statements can be pasted into eTCL console
    set testcase_1  [ eval expr  ( 1+1 +1+1)/4 ]  # 1 square meters
    set testcase_2  [ eval expr  ( 2+2 +4+4)/4 ]  # 3 square meters
    set testcase_3  [ eval expr  ( 3+3 +5+5)/4 ]  # 4 square meters
    set testcase_1_perimeter   [ eval expr  ( 1+1 +1+1) ]  # 4 square meters
    set testcase_2_perimeter   [ eval expr  ( 2+2 +4+4) ]  # 12 square meters
    set testcase_3_perimeter   [ eval expr ( 3+3 +5+5)  ]  # 16 square meters
