how many tiles of 10 cm by 6cm are needed to pave a rectangular path of 5m by 3m
pls give e whole explanation
Answers
Answer:
The area of the hallways is : 15 meters x 12 meters = 180 square meters
Step 2: Get the area of the tiles to be used.
I converted the tile dimension to meters to match up the hallway dimension.
30 centimeters = 0.30 meters
20 centimeters = 0.20 meters
Therefore, The area of the tile is : 0.30 meter x 0.20 meter = 0.06 square meters
Step 3: Divide the floor area to the tile area to get the quantity of tiles.
180 square meters / 0.06 square meters
= 3,000 pieces of 30cm x 20cm tiles is needed for a 15m x 12 m hallway.
Step-by-step explanation:
We will be using the area of rectangle formula to calculate the area o the rectangular region and the tiles.
We know that, the area of a rectangle is given by length × breadth
(a) Area of rectangular region = 100 × 144
= 14400 cm
Also, area of one tile = 5 × 12
= 60 cm2
The number of tiles needed = Area of the rectangular region / Area of one tile
= 14400 / 60
= 240
Hence, 240 tiles are needed in this case.
(b) Now, area of rectangular region = 70 × 36
= 2520 cm2
Also, area of one tile = 5 × 12
= 60 cm2
The number of tiles needed = Area of the rectangular region / Area of one tile
= 2520 / 60
= 42
Hence, 42 tiles are needed in this case.
Therefore, 240 tiles are required in 1st case and 42 tiles are required in 2nd case.
