Just count the number of squares:
(9+5)*2=14*2=28
Answer:
4
Step-by-step explanation:
As I stated, the formula of the area of a triangle is LW/2.
Meaing all you have to do is 4x2/2.
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12.
My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.
