area = l*b; % formula for area of the rectangle
fprintf('The Area of the rectangle is = %.2f\n',area); % Print the area with two decimal

b) Convert script to function

%save this file as arearec.m when call the function with pre defined variables

%example

%arearec(5,3) then press enter

%or

%if you already assign the values for l an b then you call the function as arearec(l,b)
function arearec(l,b) %define function name as arearec
area = l*b;
fprintf('The Area of the rectangle is = %.2f\n',area);
