    Multiply one side by another for the area. 3*6=

    And for the Perimeter 3+3+6+6 (add all the sides together)

    It is like a H the long part is 3 feet by 6 feet, the the inside of the H is 4 feet by 3 feet

    Hmmm.... I'm trying to understand the shape. Are both the long parts 3 by 6? and the middle part 4 by 3?

    ok. The area is found the same way. 3*6 + 3*6 + 4*3 =

    and the Perimeter you have to think about it a bit.

    http://i54.tinypic.com/2a5kbax.png - Here we need to find the length of the "?"

    the middle part is 3 feet and the long part is 6 feet. We just subtract them. 6 - 3 = 3. BUT 3 is the length of both the top "?" and the bottom "?" of one side.

    3/2=1.5 feet. There are 4 of these 1.5 parts so: 4*1.5 = 6 Feet.

    Add this 6 feet to the 32 feet we had earlier is 38 feet.
