Given:
Square tiles = 5 inches wide
Rectangular row of tiles = 9 ft by 7 inches wide
First, we need to convert the feet into inches. 1 foot = 12 inches
9ft x 12 inches/ft = 9 * 12 inches = 108 inches
We need to get the area of both shapes.
Square tile = (5in)² = 25in²
Rectangle = 108 inches * 7 inches = 756in²
756 in² ÷ 25 in² = 30.24 tiles round to 31 tiles.
