Question

My calculus teacher never showed my class how to solve this type of problem. If someone could please show me the steps for how to solve it that would be awesome and to check if I got the right answer. The dimensions I got for the least amount of fencing is:

x=squareroot(180,000)   &   y= 1350/(squareroot(2))
