Answer:
9
Step-by-step explanation:
Area of each tile = 1 square foot.
Area of the floor = Length × Breadth =
[tex]2 \frac{1}{2} \times 3 \frac{3}{4} [/tex]
=
[tex] \frac{5}{2} \times \frac{15}{4} = \frac{75}{8} = 9 \frac{3}{8} = 9.375 {ft}^{2} [/tex]
Number of tiles needed to cover the floor = Area of the floor / Area of the tiles = 9.375 / 1 = 9.375 = 9
