Answer
Given:
Length $(I)=135 m$
Breadth $(b)=65 m$
$ \text { Perimeter }=2(I+b)$
$=2(135+65)$
$=2(200)$
$=400 m $
$\therefore$ Perimeter of rectangular plot is $=400 m$
Cost of fencing per $m$= ₹ 60
$\therefore$ Cost of fencing $400\ m = ₹ 60 \times 400\ m = ₹ 24000$
Length $(I)=135 m$
Breadth $(b)=65 m$
$ \text { Perimeter }=2(I+b)$
$=2(135+65)$
$=2(200)$
$=400 m $
$\therefore$ Perimeter of rectangular plot is $=400 m$
Cost of fencing per $m$= ₹ 60
$\therefore$ Cost of fencing $400\ m = ₹ 60 \times 400\ m = ₹ 24000$
