Question

A square courtyard of 60 m has to be tiled. The side of a squared tile is 20 cm. How many such tiles will
be required for the courtyard?
​

Answer 1

Answer:

90000 tiles

Step-by-step explanation:

area of a tile = 20cm*20cm = 400cm^2

Total = 60m*60m = 3600m^2 or 6000cm*6000cm=36000000cm^2

number of tiles = area of one tile/ Total

= 36000000/400=90000

Answer is 90000 tiles
