Answer

The total cost of fencing for the rectangular field is $1456.

Work Step by Step

1. Let $P =$ fencing cost for the country road side $P = (4.25 \times 82) + (4.25 \times 126)$ $P = (348.5) + (535.5)$ $P = 884$ The fencing cost along the country roads is 884 dollars 2. Let $M =$ fencing cost for the other two sides $M = (2.75 \times 82) + (2.75 \times 126)$ $M = (225.5 + 346.5)$ $M = 572$ The fencing cost on the other two sides is 572 dollars. 3. Adding the costs Let $T =$ total cost of fencing for rectangular field $T = 572 + 884$ $T = 1456$ dollars Therefore the total cost of fencing for the rectangular field is $1456.
