i want solve this question by matlab code

%clearing window, variables and figures
clear all;
close all;
clf;
clc;
l=0:.01:144;
h=l.*(1/2^0.5); %h=lcos(45)
ba=l.*(1/2^0.5); %ba= lsin(45)
%area=b*h+h*ba;
b=(144-h.*ba)./(h);
s=min(2*l+b) %minimum P;
L=length(l);
for i=1:1:L
if(s==2*l(:,i)+b(:,i))
length=l(:,i) %length corresponding to minimum area
breadth=b(:,i) %breadth corresponding to minimum area
end
end

Result;
