Question

The length and breadth of a rectangular field are $110m$ and $85m$ respectively. Find the perimeter of the field. How much will it cost to fence the field at the rate of $Rs25$ per metre?

Answer 1

Given: Length of the rectangular field$=110m$

Breadth of the rectangular field$=85m$

Perimeter of the rectangular field$=2(l+b)$

$=2(110+85)=2\times 195$

Perimeter of the rectangular field$=390m^2$

Cost to fence the field per metre$=$Rs.$25$

Cost to fence the field $390$ metre$=$Rs.$25\times 390=Rs.9,750‬$

$\therefore$ Cost of fencing the field $=Rs.9750$
