Answer

Question 1

Explanation:

Step1: Calculate length value

Given length = 25 initially, then length = length*2, so length = 25*2=50.

Step2: Evaluate if - statement

The if statement if length != 50: is false since length is 50. So the code inside the if block forward(length) is not executed.

Step3: Execute final forward command

The command forward(100) is executed. So Tracy moves 100 pixels.

Answer:

100 pixels

Question 2

Brief Explanations:

if statements in programming are used to make decisions based on whether a certain condition is true or false. In the context of Tracy (presumably a programming - related entity), it allows Tracy to make decisions based on conditional statements.

Answer:

To have Tracy make decisions based on conditional statements
