Students an art class make square tiles that are 5 inches wide. They plan to put up a row of tiles on a wall that is 9 feet 7 inches wide. How many tiles will the students need to make?

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.
