Answer :
Answer:
You will need 2400 tiles to cover the entire floor
Step-by-step explanation:
Question 4
We have to make sure that units we are working in correspond to the same system
The floor dimensions are in meters and the tile dimensions are in cm
1 meter = 100 cm
Therefore floor length of 40 m = 40 x 100 = 4000 cm
If we place tiles of 50 cm square along this length we will need 4000 / 50 = 80 tiles along the length
The width of the floor is 15 m = 15 x 100 = 1500 cm
We can place 1500/50 = 30 tiles along the width
80 tiles length wise and 30 tiles width wise would result in 80 x 30 = 2400 tile
----------------------------------------------------------------------------------------------------
The other way to approach this problem is to first find the area of the floor and divide it by the area of each time. This may seem an easier approach but sometimes the dimensions do not allow an integer number of tiles along a side so your answer may be off
In this particular problem both approaches yield the same answer
=> (4000 x 1500) /(50 x 50)= 2400
