The length of dining hall is 15 m and breadth is 12 m .Square tiles of length 30 cm are to be fixed on the floor of the hall . How many such tiles will be needed to cover the floor ?
Answers
Answer:
200 tiles
Step-by-step explanation:
area of rectangle = l*b
= 15*12
= 180m sq.
lenght of square = 30 cm
= 30/100
=0.3m
area of square = side* side
= 0.3*0.3
=0.9m sq.
total no. of tiles required = 180/0.9
= 1800/9
= 200 tiles
Answer :
Given :
Length of the dinning hall - 15 m
Breadth of the dinning hall - 12 m
length of the square tile - 30cm
Required to find :
- Numbers of tiles required to cover the floor
Solution :
Using the above given hints let's solve this question
Length of dining hall = 15meters
Breadth of the dinning hall = 12meters
From the above two statements we can conclude that the shape of the dinning hall is in rectangular shape .
So, here we have to use the area of the rectangle formula to find the area of the dinning hall .
Hence,
Area of the dinning hall = length x breadth
= 15 meters x 12 meters
= 180 meter^2
similarly,
Now we have to find the area of the square tiles .
In the question he given that ,
length of the square tile is 30 cm
Now we have to convert this 30cm into meters .
As we know
1 centimeter = 1/100 meters
so,
30 centimeters = ? meters
=> 30/100
=> 0.3 meters .
Therefore,
Length of the square tile = 0.3 meters .
Formula
Area of the square tile = side x side
Hence,
Area of the square tile = 0.3 x 0.3
0.3 x 0.3 = 0.09 meter^2
Therefore,
Now we have to find the number of tiles required
We can find this using the below mentioned formula ;
No. of tiles required = Area of the region / Area of the tile
Therefore,
Hence using this Formula let's find the number of tiles required ;
No. of tiles required = 180 meter^2 / 0.09 meter^2
= 2000 tiles
Result :
Number of tiles required = 2000 tiles .
