Answer 1

Answer:

It will cost rs.750

Step-by-step explanation:

Given.length of tile=10cm

breadth of tile=8cm

wall length=6m

wall breadth =4m

First calculate the area of the tile.

The tile is a rectangle.

hence,Area of rectangle=length×breadth.

= 10×8

=80 sq.cm

Area of wall=length ×breadth

=6×4

=24m

Convert m into cm

24 ×100cm

=2400cm

Therefore,2400÷80

=30

No.of tiles=30

Cost of 1 tile=rs.25

25×30

=750

Ans.The cost for 30 tiles will rs.750
