Answer: Least possible will be=78×55=4290
Step-by-step explanation:
length= 1872cm
breadth=1320cm
HCF of [1872,1320] =24cm
Side of each square=24cm.
Number of square tiles paved along length= 78
Number of square tiles paved along breadth=55
Least possible will be=78×55=4290
Hence, the least possible number of such tiles are 4290.
