5. A man has a field of dimensions 256.2 m by 185.5 m. Find the area of the field. He left half of the field​

Answer 1

Length of the floor = 4.5 m = (4.5 × 100) cm = 450 cm Width of the floor – 3.6 m – (3.6 × 100) cm = 360 cm ∴ Area of the floor – (450 × 360) cm2 = 162000 cm2 Side of a square tile = 6 cm ∴ Area of one square tile = (6 × 6) cm2 = 36 cm2 Number of tiles required to cover the floor = Area of floor/ Area of one tile = 4500 Now, cost of one tile = ₹ 23.25 ∴ Cost of 4500 tiles =₹ (23.25 × 4500) = ₹ 104625Read more on Sarthaks.com - https://www.sarthaks.com/787662/floor-long-and-wide-square-tile-costs-what-will-the-cost-to-cover-the-floor-with-these-tiles?show=787665#a787665
