Question

A courtyard area is 450 square meter,how many tiles of size50cm

Answer 1

area of courtyard=450x450m²

size of tile=50/100m=0.5m
area of tile=0.5x0.5 m²=0.25 m²

0.25m²-------- 1 tile
1m²------------1/0.25 tiles
450m²-----1/0.25x450 tiles=1800 tiles

Answer 2

Answer:

Area of courtyard = 450 square meter

Size of each tile is 50 cm

Area of each tile = 50*50 = 250 meter square

Tiles covered courtyard = 450*250 = 112500

We need 1,12,500 tiles to covered courtyard...
