Well, we need to find the area of the cake. 22.5 times 10 is 225. That is the area then we need to find the area of each piece of cake. 2.5 times 2.5 is 6.26.
so divide the area of the cake by the area of each piece to find how many pieces can be cut.
225/6.25=36 36 pieces of cake can be cut from the cake
Im so sorry but I didn't learn that yet
The area is 13.
I think you were on the right track there. The area of the one on the bottom is 4*1, or 4. The area of the top upright rectangle is 9*1, or 9. 9+4=13.
