Optimization Problem Using Derivativez - Q7

Question: A rectangular plot farmland will be bounded on one side by a river and on the other three sides by a single-strand electric fence. With 800m of wire at your disposal, what is the largest area you can enclose, and what area its dimensions?

Great video, but it should be 80,000 m^2 instead of cm^2

at 5:51 why A(200) ?

+Dzahinarif Yusrizal, Because we already found out x=200 as the maximum area, so we substitute x=200 inside the function for area, A(x). That's why we have A(200)
