Sep 2, 2018 · The range is 19.2 - 1.1 = 18.1. We divide 18.1 / 5 = 3.62. This means that a class width of 4 would be appropriate. Our smallest data value is 1.1, so we start the first class at a point less than this. Since our data consists of positive numbers, it would make sense to make the first class go from 0 to 4. First measure the length and width of the larger section labelled A, then do the same for the smaller section labelled B. A: 14ft × 10 ft = 140 sq. ft. B: 6 ft × 5 ft = 30 sq. ft. Now, add both values to calculate the square footage of the room: 140 sq.ft. + 30 sq.ft = 170 sq. ft. So you'll need 170 sq. ft. of flooring materials for this room.John S Kiernan, WalletHub Managing EditorAug 18, 2022 Debt is unquestionably a double-edged sword.
