Answer :
Final answer:
By calculating the area of the 2m by 1.5m floor and the area of a 25cm square tile, we find that 48 tiles are needed. The options provided in the question contain a typographical error since none of the options match the calculation.
Explanation:
To determine how many 25cm square tiles are needed to cover a 2m by 1.5m floor, we need to calculate the area of the floor and the area of a single tile, and then divide the floor's area by the area of a tile. First, convert the measurements to the same units, so 2m is 200cm and 1.5m is 150cm.
Area of the floor = length × width = 200cm × 150cm = 30,000cm².
Area of a tile = 25cm × 25cm = 625cm².
The number of tiles needed = (Area of the floor) / (Area of a tile) = 30,000cm² / 625cm² = 48.
Thus, the answer is not listed in the options provided, and it might be a typographical error in the question options.
