A program uses a turtle to draw a square.

The turtle is ready to move and draw as shown in the picture.

Here is an algorithm to draw a 25 cm

square:

Move the turtle forward degree cm.

Then turn the turtle 90 degree right.

Move the turtle forward degree cm.

Then turn the turtle degree right.

Move the turtle forward 25 cm.

Then turn the turtle 90 degree left.

Move the turtle forward 25 cm

write down the step which made the program to have an error from the steps above

Write the first line of code for this

algorithm using LOGO coding.

Here is an algorithm to draw a 25 cm

square:

Move the turtle forward 25 cm.

Then turn the turtle 90° right.

Move the turtle forward 25 cm.

Then turn the turtle 90° right.

Move the turtle forward 25 cm.

Then turn the turtle 90° left.

Move the turtle forward 25 cm.

Write a new command to complete

the square successfully by replacing the error
