                           Change the steps from 10 to 100 mention to change the degree from 15 to 90.

                  Step 13:  In the repeat block, click and change the number of repeats from 10 to 4. Why are we
                           doing this? We know that a square has 4 sides.


                  Step 14:  If you do not want the sprite to appear over the figure, you can end the code here. But

                                                                                     In Scratch, each number is
                                                                                     equal to 1 step of the sprite
                                                                                     on the stage. So, these 100
                                                                                     steps form one side of the

                                                                                     change the degree from 15
                                                                                     to 90. Why are we changing

                                                                                     the  degree?  Remember,

                       Drawing a Rectangle in Scratch

                  To draw a rectangle in Scratch, follow the same code you used to draw a square. In the repeat
                  block, change the values of the Repeat and Motion blocks as shown in the given code.

                  You can also draw a multi-coloured rectangle. To do so, remove the            set pen color to    block

                  and place the block       Change pen color  by 10  in the Repeat block. Change the value from 10
