Question

What is the cost of tiling a rectangle plot of land $500m$ long and $200$m wide at the rate Rs$8$ per hundred sq.m?

Answer 1

Length of rectangular plot$=l=500$m

Breadth of rectangular plot$=b=200$m

Area of rectangular plot$l\times b=500\times 200=1,00,000$sq.m

Cost for tiling $1$sq.m$=$Rs.$\frac{8}{100}$

Cost for tiling $1,00,000$sq.m$=\frac{8}{100}\times 1,00,000$rs.$8\times 1000=$Rs.$8,000$

$\therefore$ It will cost Rs.$8,000$
