Then multiply the area by the number of tiles per square foot to find the total number of tiles needed: 250 feet * 4 tiles / square foot = 1000 tiles. Then multiply the number of tiles by the percentage that are green to find the total number of green tiles: 1000 tiles * 40% = 400 tiles. Subtract that number from the total number of tiles to find the number of red tiles: 1000 tiles - 400 tiles = 600 tiles. Multiply the number of red tiles by the price per red tile to find the cost of the red tiles: 600 tiles * $1.50 / tile = $900. Multiply the number of green tiles by the price per green tile to find the cost of the green tiles: 400 tiles * $3.00 / tile = $1200. Then add the cost of each type of tile to find the total cost: $900 + $1200 = $2100. Final answer: 2100. <hau> Da farko ka gano yankin farfajiyar: 10 feet * 25 feet = 250 feet.
