Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
Find total area
area=14 ties 12=168 ft^2
9 hours
168/9=56/3=18.6666666 ft^2 per hour
round
18.7 ft^2 per hour
4,800
