The program below attempts to draw a blue rectangle but does not work as intended. What change needs to be made for the blue rectangle to be drawn? Options: drawRect; should be at the end of the program, fill("blue"); should be moved outside of the function and after drawRect;, fill("blue"); should be moved outside of the function and before drawRect;, drawRect; should be drawRect();, rect(0, 300, 200, 50); should be rect(0, 300);

Back

drawRect; should be drawRect();

Front

The program below draws the scene on the right, but you want the rectangle to be further to the right. How can you change the code to achieve this? Options: Call .moveRight(), Add a line of code to change rect.x = 100;, Update the first argument (parameter) of rect( ) to 100, No change needed: the rectangle is animated to move right

Back

Update the first argument (parameter) of rect( ) to 100
