Answer 1

Step-by-step explanation:

area of lawn=12*10=120m

120*100=12000cm Square

require tiles=12000/25=480tiles

Total cost =480*8=3840Rs

Answer 2

Step-by-step explanation:

Area of floor tile = Side X Side

= 25cm X 25cm

Area of rectangular lawn = l X b

= 12m X 10m

$= 120 {m}^{2}$

Area of rectangular lawn in cm = 120 X 100 X 100

$number \: of \: tiles \: = \frac{area \: of \: rectangular \: lawn}{area \: of \: \: 1 \: tile}$

$= \frac{120 \times 100 \times 100}{25 \times 25}$

= 1920 tiles

cost of 1 tile = Rs. 8

cost of 1920= Rs. 8 X 1920

= Rs. 15360
