How much wire does Joe need to have a four-strand fence enclosing a rectangular field that has the dimensions of 1/3 mile by 1/4 mile?

Answer 1

Well, Let's have some fun with this...

the perimeter is 2(1/3) + 2(1/4)

= 2/3+2/4

= 2/3+1/2

= 4/6 + 3/6

= 7/6

Multiplies by 4:

7/6 * 4 = 28/6 = 14/3

So 14/3 MILES of wire is needed !!!

4 and 2/3 miles of wire is needed

That is the answer to the question....

=======================================================

The Home Depot sells barbed wire for $70 per roll and

each roll contains 1320 feet, and that is the CHEAP stuff!

1 mile = 5280 feet

4 and 2/3 miles = (4 and 2/3) * 5280

= 14/3 * 5280

= 14* 5280/3

= 14 * 1760

= 24640 feet

24640/1320 = 18 and 2/3 rolls are needed

18 and 2/3 * $70 = $1306.67
