Math problem solving investigation: guess and chec
no idea how many squares you have, but start counting. If there are n squares larger than the smallest, then the area of the largest is 3*2^n. The areas are: 3,6,12,24,48,96,... If you want to ask questions about diagrams, you gotta describe what's going on here.
