Question

A rectangular count yard is 18m 72cm long and13m20cm broad. It is be proved with square tiles of the same size. Findthe least possible number of such tiles

Answer 1

length of the courtyard = 18m72cm or 1872cm
breadth of the courtyard = 13m20cm or
1320cm
now, size of 1 square tile = HCF OF L and B ²
=24²
so number of tiles = area of courtyard/area of
tile
= (1320×1872) ÷ (24×24)
= 2471040 ÷ 576
= 4290
Answer = 4290 tiles
hope it helps!
