You can make a rectangle by using two squares
let say a is the width and b is the length then 2(a+b)=30 or (1)a+b=30 and the biggest rectangle is the one having the biggest area So (2) A=axb should be max From (1) a=30-b then using (2) A=(30-b)*b = 30b-b2 So the next point is to study the function f(x)=30x-x2 it's derivative is f'(x)=30-2x which change sign at 30/2=15 so 15 is the maximum The maximum area is 225, b=15 then a=15 Then the biggest rectangle with a perimeter of 30 is a square!

A train but with a big rectangle.

yes you can just get your biggest figure and cut a rectangle the size of the figure and just do the rest however you want
