%First Program  
pi=3;
kenar1=input('dikdörtgenin uzun kenarının boyunu giriniz: ');
Unable to run the 'fevalJSON' function because it calls the 'input' function, which is not supported for this product offering.
kenar2=input('dikdörtgenin yüksekliğini giriniz: ');
alan= kenar1*kenar2;
daire=pi*(kenar2/2)^2;
alan;
alan2=alan/2-daire;
disp(['Dikdörtgenin alanı:  ',num2str(alan)])
disp(['Kırmızı bölgenin alanı:  ',num2str(alan2)])

Hi @Bünyamin Bora

The formulas are generally correct. However, there is a technical issue worth considering. Have you ever wondered why the area of the red region is 0 when the length is 3 and the height is 2?

There will be another issue after you fix it.

%First Program  
pi      = 3;                % what is 'pie' 🥧?
side1   = 3;                % input( 'Enter the length of the long side of the rectangle: ' );
side2   = 2;                % input( 'Enter the height of the rectangle: ' );
area    = side1*side2;      % area of the rectangle
circle  = pi*(side2/2)^2;   % formula to calculate area of a perfect circle
area2   = area/2 - circle;  % area of red region
disp(['Area of ​​the rectangle:  ', num2str(area)])
Area of ​​the rectangle:  6
disp(['Area of ​​the red region: ', num2str(area2)])
Area of ​​the red region: 0
