Question 1:The lengths of AB and AD can be determined by measuring them (since they're horizontal).
AB = 3
AD = 9

Your answer is 3.
Question 2:
The slope of BE can be found using the slope formula.

Just plug in two points from BE and you get 5.
Use that same formula for AE and you get 5/4
Now, plug them into the fraction.

That's your answer.
Hope this helps! :)
