Find the least number of square tiles to cover the room floor, which has length of 5 meter and 44 cm and width of 3 meter and 74 cm.
Answer: A . 176Tweet
Area of the room A = 544 * 374 Sq. cm
To find the numbee of square tile, it is required to find Highest Common Factor (HCF) of the length and width, which is 34, because the tiles are square, the area of tiles a - 34 * 34 Sq. cm
So, the number of tiles = A / a = (544 * 374) / (34 * 34) = 16 * 11 = 176 tiles are required.
