Answer the following question, with explanation first.
The largest room in Mrs. McAvoy's house is 45 feet wide and 30 feet long. The smallest room in that same house is 15 feet wide and 8 feet long. What is the difference in area between the largest room and the smallest room?

1230
The area of the largest room is 45 ft x 30 ft = 1350 sq ft.

The area of the smallest room is 15 ft x 8 ft = 120 sq ft.

The difference between the two is 1350 sq ft - 120 sq ft = 1230 sq ft.

.

Therefore, the answer is 1230
