    Visually speaking, if you move the 4 cm leg right to form a rectangle, you'll see that your horizontal sides are 7 cm and your vertical sides are 9 cm.

    Since you add the lengths of all sides to get the Perimeter, you have: 

    P = (7 + 7) + (9 + 9)

    P = 14 + 18

    P = 32 cm

    The two other sides are 4cm and 9cm

    Perimeter: 4+9+7+5+3+4 = 32.0cm

    Vertical  lines

    (5 + 4) + 9 = 18

    Horizontal lines

    7 + (3 + 4) = 14

    Total

    18 + 14 = 32cm <–––––
