Question

The length and breadth of a hall is 80m and 60m . find the number of 20cm square tile required to pave the hall?​

Answer 1

Answer:

number of tiles required = 120000

Step-by-step explanation:

area of the floor = l * b

which is,

80 * 60 = 4800 $m^{2}$

side of one square tile = 20 cm or 0.2 m

area of square tile = 0.2*0.2

which is,

0.04 $m^{2}$

let n be number of tiles required so,

4800 = n * 0.04

therefore ,

n = $\frac{4800}{0.04}$

which is,

120000 tiles
