Perimeter and Area

Room 10 has been working on Perimeter and area.  This was my shape.  For the perimeter I did 6+4+4+3+2+1+3+2+1+1+2+1=32
For the area I did 5x1=5  3x1=3  3x1=3 1x1=1 1x1=1  2x2=4.  After that I went 5+3+3+1+4+1=17.

Perimeter is the distance around the shape and area is the surface  in the middle of the shape like my one.
