Question 275225: A rectangular lot whose perimeter is 1600 feet is fenced along three sides. An expensive fencing along the lots length costs $20 per foot. An inexpensive fencing along the two sides costs only $5 per foot. the total cost of the fencing along the three sides is $13,000. What are the lots dimensions?

Let the length of the fence be X
then the width is 800 - X
Cost is 20X +2x5x(800 -X) = 13000
20X + 8000 - 10X = 13000
10X = 5000
X = 500
So the length is 500 feet and the width is 300 feet
