• There are 8 columns and 7 rows, so you should subtract 8 – 7 to get 1 rectangle

• There are 7 rows and 8 columns, so you should multiply 7 × 8 to get 56 square inches

• D. There are 8 columns and 7 rows, and you add the 8 from top and bottom and the 7 from both sides to get 8 + 8 + 7 + 7 to get an area of 30.
