Q. Angela is building a pool that is 25 meters long. She has selected tiles to put around the edge of the pool. If each tile is 8 inches long, how many tiles does she need for one 25-meter side of the pool?
Convert to inches: First, we need to convert the length of the pool side from meters to inches, because the tile length is given in inches. There are 39.37 inches in a meter.So, we calculate the length of the pool side in inches.25 meters×39.37 inches/meter=984.25 inches
Calculate total tiles needed: Next, we divide the total length of the pool side in inches by the length of one tile to find out how many tiles are needed.984.25 inches / 8 inches/tile = 123.03125 tilesSince we can't have a fraction of a tile, we'll need to round up to the nearest whole tile.
Round up to whole tile: We round up 123.03125 to the next whole number, which is 124. So, Angela needs 124 tiles for one 25-meter side of the pool.
