Answer:
10 tiles
Explanation:
Since the row the students plan to make is 4 feet 2 inches long, we need to first convert the feet into inches since the tiles they plan to make are measured in inches. Since there are 12 inches per foot, we can multiply:
12 inches x 4 feet = 48 inches
48 inches + 2 inches = 50 inches
Since each tile is 5 inches long, we can take the total length and divide by the length of each tile to find the number needed:
50 ÷ 5 = 10 tiles
