Question

What is the post of tiling a rectangular field 500 m long and 200 m wide at the rate of Rs. 7.5 per hundred square metres?

Answer 1

Length of the rectangular field $=500m$
Breadth of the rectangular field $=200m$
$\therefore$ Area of the rectangular field = Length $\times$ Breadth
$=500m\times 200m=10000sq.m$
$\because$ Cost of tiling $100sq.m=Rs.7.5$
$\therefore$ Cost of tiling $1sq.m$ = Rs.$\frac{7.5}{100}$
$\therefore$ Cost of tiling 100000 sq. m = Rs.$\frac{7.5}{100}\times$ $100000=Rs.7500$
