Question

A hall has length 28meter and breadth 10.5meter.For flooring this hall,square tiles are to be used pf half meter side then how many tiles are required?​

Answer 1

Answer:

The number of tiles required in flooring is 1176  .

Step-by-step explanation:

Given as :

Let The number of tiles required = n tiles

The length of the hall = L = 28 meters

The width of the hall = B = 10.5 meters

Area of the rectangular hall = Length × width

i.e Area of hall = L × B

Or, Area of hall = 28 m × 10.5 m

∴ Area of hall = 294 m²

Again

square tiles are used for flooring the room

The each length of square tiles = l = 0.5 meters

Area of square tiles = side × side

Or, Area of tiles = l × l

Or, area of tiles = 0.5 m × 0.5 m

∴ Area of tiles = 0.25 m²

Now

The number of tiles required = $\dfrac{Area of hall}{Area of tiles}$

i.e n = $\dfrac{294}{0.25}$

Or, n = 1176

So, The number of tiles required = n = 1176

Hence, The number of tiles required in flooring is 1176  . Answer

Answer 2

$=1176$ tiles

Step-by-step explanation:

given, dimension of hall length=28 meter,breadth=10.5 meter and tiles are in square in shape whose side is =.5 meter

area of hall=$l\times b$

                   $=28\times 10.5$

                   $=294m^{2}$

area of tile   $=.5\times 5$

                   $=.25 m^{2}$

let   n,   number of tiles be  used in for flooring the hall

n$\times$ area of tiles=area of hall

                $n\times .25=294$

                       $n=294/.25$

                          $=1176$
