Answer:
1) 1 m² = 10.75 tiles
2) 10 m² = 107.5 tiles
3) 9.3 m² of tiles = 100 tiles
4) a m² = 10.5a tiles
Explanation:
The table is missing and so i have attached it.
From the question, we are told that each square meter of ceiling requires 10.75 tiles. Thus on the first row;
1 m² = 10.75 tiles
The second row of the table shows 10 m² of tiles.
Thus, by proportion, 10 m² of tiles will require; 10 × 10.75 tiles = 107.5 tiles
The third row shows us 100 tiles required.
Since 10.75 tiles is for 1 m² , then by proportion, we can find the square meters of tiling of 100 tiles. Thus;
100 tiles will use; 100 × 1/10.75 = 9.3 m² of tiles
The fourth row shows us square meter of tiles to be a.
Thus by proportion, number of tiles required for this square meter of tile is;
a × 10.75/1 = 10.75a tiles
