Help with this math homework

Answer 1

You should try doing this:

Count the smallest amount of tile on one side of the square.
There are eight, and 8X8=64 smallest tiles.

Next, the next to smallest amount of tiles have four smallest tiles, there are two smallest tiles on the side of a next to smallest tiles square. Because of that, there is (8/2=4) next to smallest tiles, and 4*4 = 16

And so on

4/2 = 2
2*2 =4

2/2 =1
1*1 =1

Then you add up all the squares of all the different size possible:

64+16+4+1 = 85 squares
