Question

the area of a balcony is 400 CM x 500 cm how many tiles of 20 CM X 50 cm and needed to cover the entire floor of balcony​

Answer 1

Area of balcony = 200,000 cm².

Area of one tile = 1,000 cm²

So, number of tiles required = area of balcony/area of one tile

= 200,000/1,000

= 200

Hence, number of tiles required is 200.
