For part (a),

• first variables width and height both of type int are declared;
• then width is assigned the value 4;
• then height is assigned the value width*2, i.e. 8;
• then the variable area of type int is declared and assigned the value resulting from the product of the values of width and height, i.e. 4*8, which is 32;
• finally the value of area, i.e. 32, is displayed in the Output window.
