Sure, let's solve the problem step by step.
First, let's calculate 3 times 9:
3 * 9 = 27
So, 3 times 9 equals 27.
Now, let's count the squares in the tile design.
There are small squares and large squares.
Let's count the small squares first. Looking at the design, it seems there are 3 small squares in each row, and there are 9 rows in total.
So, the number of small squares = 3 * 9 = 27.
Now, let's count the large squares. Each large square comprises 9 small squares.
So, the number of large squares = 1 * 1 = 1.
Adding up the number of small squares and large squares, we get:
Total number of squares = 27 (small squares) + 1 (large square) = 28.
So, there are 28 squares in the design.
