Anyway, here's the task/test I need to complete, trying to translate it from Estonian to English the best way I can.

So far I have understood that the area of the plot is 2312 meters squared. I have marked the area as S, so I have gotten S=2312m2. The formula for the area calculation should be S= a * b. I have set "a" as the length of the fence that should be the minimum, how should I proceed?Rectangular cottage plot with area 2312m2 , must be fenced off on three sides. Find the plot dimensions so that the length of the fence is the shortest.

The length of the fence is *blank* meters, the width is *blank* meters

Thank you for your time and help, I really appreciate it and thanks in advance!! Sorry if this is in the wrong section, maybe someone can move it?
