How many tiles whose length and breadth are 13 cm and 7 cm respectively are needed to cover a rectangular region whose length and breadth are 520 cm and 140 cm?
Answers
Answer :
- 800 tiles are required to cover the region
Given :
Rectangular tiles :
- length is 13cm
- breadth is 7cm
Rectangular region :
- length is 520 cm
- breadth is 140 cm
To find :
- tiles
Solution :
Rectangular tiles :
- Length of tile is 13cm
- breadth of tile is 7cm
As we know that ,
- Area of rectangular tiles = length × breadth
● 13 × 7
● 91 cm²
Area of rectangular tiles is 91cm²
Rectangular region:
- length of region is 520 cm
- breadth of region is 140cm
As we know that ,
- Area of rectangular region = length × breadth
● 520 × 140
● 72800cm²
Area of rectangular region is 72800cm²
Now , we have to find the numbers of tiles :
- Number of tiles = Area of rectangular tiles - Area of rectangular region
● 72800/91
● 800
Hence , 800 tiles are required to cover the region
Step-by-step explanation:
Answer :
800 tiles are required to cover the region
Given :
Rectangular tiles :
length is 13cm
breadth is 7cm
Rectangular region :
length is 520 cm
breadth is 140 cm
To find :
tiles
Solution :
Rectangular tiles :
Length of tile is 13cm
breadth of tile is 7cm
As we know that ,
Area of rectangular tiles = length × breadth
● 13 × 7
● 91 cm²
Area of rectangular tiles is 91cm²
Rectangular region:
length of region is 520 cm
breadth of region is 140cm
As we know that ,
Area of rectangular region = length × breadth
● 520 × 140
● 72800cm²
Area of rectangular region is 72800cm²
Now , we have to find the numbers of tiles :
Number of tiles = Area of rectangular tiles - Area of rectangular region
● 72800/91
● 800
Hence , 800 tiles are required to cover the region
