Answer

Perimeter of fied =2(l+b)

=2(450+250)

=2(700)

=1400m

Cost of fencig 1 meter-50paise

Cost of fencing field-1400*50-70000paise-Rs.700

Length = 450 m

Breadth = 250 m

Perimeter of a rectangle =  2(l + b)

∴ Cost of fencing = (Perimeter)(Rate)

=> Cost = Rs [2(450 + 250)] × (0.5)

{1 Re = 100 Paise.}

=> Cost = Rs ½(1400)

=> Cost = Rs 700.

Therefore, a) Rs 700 is the correct option.

More: Area of rectangle =  l.b .
