GIVEN:-
length = 21 (3/4) = 87/4m
breadth = 11 (1/4) = 45/4m
side of square tiles = 3/4m
now,
area of hall = (length × breadth)
= (87/4 × 45/4)
= (3915/16)
= 3915/16 m²
similarly,
area of square tiles = 3/4 × 3/4 = 9/16m²
thus, tiles are required to pave the floor of the hall = area of hall /area of tiles.
=> {(3915/16)m²}/{(9/16)m²}
=> 3915m²/9m²
=> 435 tiles
hence, tiles are required to pave the floor of the hall = 435

Step-by-step explanation:
l×b=87/4×47/4
side×side=3/4×3/4
number of tiles= l×b/side×side
=87*47*4*4/3*3*4*4
=29*47/3
=1363/3
=454 tiles
