Anyone know the answer to all of these

13:
A- The scale factor is 16 (80/5)

14:
A- The scale factor is 6 (30/5)
B- The perimeter of the scale drawing is 14 feet (5x2) + (2x2)
C- The area of the scale drawing 10 ft. sq (base x height) (5 x 2)
D- The perimeter of the actual screen is 84 feet (30x2) + (12x2)
E- The area of the actual screen is 360 ft. sq (base x height) (30 x 12)

Hope this helped you out tons! :D

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
