Answers
Step-by-step explanation:
QUESTION :
How many tiles are required to covered the rectangular region.
GIVEN :
length of tiles = 13 cm
breadth of tiles = 7 cm
Length of rec region = 520 cm
Breadth of rec region = 140 cm
FORMULA USED HERE :
Area of rectangle = l × b
SOLUTION :
l of tile = 13 cm
b of tile = 7 cm
area of tiles = l x b
= 13cm x 7cm
= 91 cm²
Now,
l of rec region = 520 cm
b of rec region = 140 cm
area of rec region = 520 cm x 140 cm
= 72800cm²
Again,
Number of tiles required = area of tiles / area of rec region
than,
72800cm² / 91 cm²
= 800 Answer
Hence, 800 tiles is required

Genius , just try to understand step by step ,
Answer :
800 tiles
Step-by-step explanation:
Area of the tiles = Length × Breadth
= 13 × 7
= 91 cm²
Area of the rectangular region = Length × Breadth
= 520 × 140
= 72800 cm²
Therefore the number of tiles needed to cover the rectangular region
= Area of the rectangular region ÷ Area of the tiles
= 72800 cm² ÷ 91 cm²
= 800 tiles
Hope this helps you !!!
