Answer:
1920 tiles, cost is 15360
Step-by-step explanation:
25 cm = 1/4 m
area of 1 square tile = 1/4 × 1/4 = 1/16 m²
total area of lawn = 12 x 10 = 120 m²
so number of tiles needed = total area of lawn ÷ area of 1 square tile
number of tiles needed = 120 ÷ 1/16 = 1920 tiles
total cost = 1920 x 8 = 15360
