Answer 1

. To pave the courtyard 54 tiles required

Answer 2

hey mates your answer is here

Length = 1872 cm

Width = 1320 cm

The edge of the square tile must be the common divisor of the dimensions of the courtyard.

So, maximum edge of square tile = HCF of 1872 and 1320 = 24 cm

So, required number of tiles = area of courtyard/ Area of square tile = 1872 x 1320/ (24)2 = 4290

Thus, the least number of tiles required to cover the courtyard is 4290.
