Answer 1

$\huge{\boxed{\mathcal\pink{\fcolorbox{red}{white}{SOLUTION}}}}$

length of the field = 62m

width of the field =80m

so,

the perimeter of the field = 2(l+b)

= 2(62m+80m)

= 2× 142m = 284m

cost of wiring + labouring 1m = 50+ 1250rupee

= 1300rupee

so, the cost of "284m" = 1300 ×284 rupee

= 3692rupee

cost of fencing is "3692rupee"
