Answer» Given length of hall = 20m 20cm = 2020cm. Given breadth of hall = 12m 40cm = 1240cm. Now, The size of square tiles will be the HCF of 2020 and 1240. = > HCF of 2020 and 1240 = 2 * 2 * 5 = 20cm. Now, Area of each tile = 20 * 20 = > 400 cm^2. The required number of tiles = Area of hall/Area of each tile = > (2020 * 1240)/400 = > 6262.

Answer»

Given length of hall = 20m 20cm = 2020cm.

Given breadth of hall = 12m 40cm = 1240cm.

Now,

The size of square tiles will be the HCF of 2020 and 1240.

= > HCF of 2020 and 1240 = 2 * 2 * 5 = 20cm.

Now,

Area of each tile = 20 * 20

= > 400 cm^2.

The required number of tiles = Area of hall/Area of each tile

= > (2020 * 1240)/400

= > 6262.
