Question

A rectangular path of 60m long and 3m wide is covered with square tiles of side
25cm. How many tiles will there be in one row along its width? How many such rows
will be there? Find the number of tiles used, to make this path.

Answer 1

Answer: Let L and B are the length and breadth of rectangle

Given that L=60 m=6000 cm

B=3 m=300 cm

Side of the square tile =25 cm

Number tiles will there be in one row along its width

⇒

side of the a tile/width of the path

= 300/25

=12

Number of the rows = side of a tile/ length of the path

= 6000/25

=240.

Total number of tiles used = 240×12=2880

Answer 2

Answer:

Given, length of path = 60 m

and width of path = 3 m

Side of square tile = 25 cm =

25

100

m= 0.25 m [

∵

1 m= 100 cm]
