Answer:
Step-by-step explanation:
given,
rectangular floor
l = 9 m
b = 6 m
black tiles
l = 40 cm
b = 10 cm
rectangular floor,
9m = 900cm
6m = 600 cm
area of floor = l × b
= 900× 600
=540000 cm sq.
black tiles area = l × b
= 40×10
= 400 cm sq.
no of tiles = area of rectangular floor ÷ area of tiles
= 540000/ 400
= 1350 tiles
No. of tiles = 1350 tiles
