Answer 1

Step-by-step explanation:

Area of floor = l × b

• 2m = 200 cm.
• 1.5m = 150 cm.

200 × 150 = 30,000.

Area of the tiles = l× b

• 25 × 25 = 625cm sq.

No. of tiles for floor = area of floor / area of tiles.

No. of tiles for floor = 30,000/ 625 = 48 tiles

Cost of 12 tiles = $ 420.

• Cost of 1 tiles = 420/12.
• cost of 48 tiles = 420/12 × 48 = $ 1260.

I Hope it's helpful for all of you.
