Question

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?

Answer 1

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.
