For perimeter, add all sides. 3+4+10+12+(6)+(8)
You find 6 because one side is 10 and the other is 4
12-4 is 8.
Add them all and you get 43 PERIMETER
For area, pretend that it is a whole rectangle-solve that are
10*12 is 120
The are of the empty are is 4*8 = 32
120-32 is 88- are
PERIMETER IS 43
AREA IS 88
