Answer 2

Cost of polish would be Rs. 229775.

Step-by-step explanation:

Since we have given that

Length of table top = 5 m 5 cm = 505 cm

Width of table top = 9 m 10 cm = 910 cm

So, area of table top would be

$Length\times breadth\\\\=505\times 910\\\\=459550\ cm^2$

Cost of per square cm = 50 paise

So, total cost would be

$\dfrac{50}{100}\times 459550\\\\=0.5\times 459550\\\\=Rs.\ 229775$

Hence, cost of polish would be Rs. 229775.
