Answer:

9.first we will find the total area

: 6×36/10=21.6

now we will divide it by area of 1 tile

Sorry mate i didn't know question number 8 sorry.....

Answer 2

Step-by-step explanation:

2. Area of wall=l×b => 9.5×8 => 76m².

Area of square shaped pictures=a²=> 4²=16m².

Remaining area=76-16=60m².

Painted at rate:

1m²=22.Rs

60m²=22×60=1320.Rs

9.Area of rectangular lawn=l×b=> 6×3.6=21.6m²

Area of each tile=a²=> (1.2)²=1.44mm².

Numbers of tiles=21.6/1 44=15.

Total cost of laying glass tiles in lawn:

1 tile=18.Rs

15 tiles =15×18=270.Rs.
