Sidana [21]

Answer: $2250

Dimension of the room = 20 feet × 15 feet

Cost of tiles = $7.50 / ft²

<u>Derived formula from the given information</u>

Total cost = Floor area × Cost of tiles

Total cost = Floor area × Cost of tiles

Total cost = (20 × 15) × (7.5)

<u>Simplify by multiplication</u>

Total cost = 300 × (7.5)

\Large\boxed{Total~cost~=~2250~Dollars}
