Question

Antonio will use 10 large 3/4-foot by 3/4-foot white tiles to cover the white part of the wall. Each of the blue squares shown will be tiled using numerous smaller 3-inch by 3-inch blue tiles to cover the blue part of the wall. How many of the smaller blue tiles will Antonio need to cover the 14 blue squares on the kitchen wall?

Answer 1

Answer:

126 tiles

Step-by-step explanation:

The while tiles are 3/4 of a foot (or 9 inches) x 9 in, so their area is 81 sq in. There are 14 blue tiles, so 14 x 81 = 1134 sq inches that need to be covered.

Each tiles is 3 x 3, so its area is 9 sq in. 1134 / 9 = 126 tiles
