Question

10. want to have a fencing round a piece of land 80
metres long 64 metres wide. What will be the
weight of barbed wire if 4 metres of barbed wire
weights 12 kilogram?​

Answer 1

Answer:

864 kg

Step-by-step explanation:

total wire to me fenced = perimeter of rectangle

=》 2(L+B)

= 2( 80+64)

= 2 × 144

= 288 meters

now

if cost of 4 meters wire = 12kg

so cost of 1 m wire = 12/4 = 3 meters

so cost of 288 meters wire = 288×3 = 864 kilograms

Answer 2

Answer:

864 kg is the right answer
