All as length 28 and breadth 10.5 metre for flooring this all square tile are to be used of half metre side then how many tiles are required

Answer 1

1176

Step-by-step explanation:

area of hall=28*10.5=294

no of tiles required= area of hall upon area of tiles

294/0.25

=1176

Answer 2

The total number of square tiles = 1176

Step-by-step explanation:

Given,

The length of hall (l) = 28 metre and

The breadth of hall (b) = 10.5 metre

The side of square tile (a) = $\dfrac{1}{2} m$

To find, the total number of square tiles = ?

∴ The area of the hall = 28 metre × 10.5 metre

= 294 $m^{2}$

The area of square tile = $\dfrac{1}{2} m$ × $\dfrac{1}{2} m$

= $\dfrac{1}{4}$ $m^{2}$

∴ The total number of square tiles $= \dfrac{The area of the hall }{The area of square tile}$

= $\dfrac{294 }{\dfrac{1}{4}}$

= 294 × 4

= 1176

Thus, the total number of square tiles = 1176
