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?
The area of the largest room is 45 ft x 30 ft = <<45*30=1350>>1350 sq ft
The area of the smallest room is 15 ft x 8 ft = <<15*8=120>>120 sq ft
The difference between the two is 1350 sq ft - 120 sq ft = <<1350-120=1230>>1230 sq ft
