Hannah has a grid of squares that has 12 rows with 15 squares in each row.She colors 5 rows of 8 squares in the middle of the grid blue.She colors the rest of the squares red. How many squares does Hannah color red?
Okay so the total number of squares would be 12 x 15 which equals 180 squares. The part she colors blue is 5 x 8 which equals 40 squares. So 180 - 40 would equal 140 squares that she colored red.
