Question

if 800 feet of fencing is used to enclose a rectangular plot of land that borders a river, what is the maximum area that can be enclosed?

Answer 1

Below

Explanation:

The maximum area of land that can be enclosed is a SQUARE

using the river as one side of the square means there are 3 sides that total 800 ft 800 / 3 = 266 2/3 ft per side

area would then be L x W = 266 2/3 * 266 2/3 = 71111 1/9 ft^2
