# Chapter 8 - Geometry - 8.3 Rectangles and Squares - 8.3 Exercises: 30

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 + 884T = 1456$dollars Therefore the total cost of fencing for the rectangular field is$1456.
