Question 1076809
What do you mean it could be 4 feet?



Is it 9 feet or 4 feet?



Let A = rectangular surface area



Use the formula: A = 2(wh + Lh + Lh)



Rewrite 5_1/2 as 11/2 for easy calculation.



If the height is 9 feet, use the following set up:



A = 2[(11/2)(9) + (6)(9) + (6)(9)]



If the height is 4 feet, use the following set up:



A = 2[(4)(9) + (6)(9) + (6)(9)]



You finish.
