Answer:
4,240 tickets
Explanation:
The first level of standing room is a square with one side measuring 80'.
Area of the first level = length^2
= 80^2
= 6,400 square ft
The second level, also standing room, is a rectangle measuring 120' by 30' ft.
Area of the second level = length × width
= 120 × 30
= 3,600 square ft
Total area of the standing rooms = (6,400 + 3,600) square ft
= 10,000 square ft
Each person in the standing room will occupy 2.5 square ft
Number of Persons that will occupy the standing room = Total area of the standing rooms / 2.5 square ft
= 10,000 square ft / 2.5 square ft
= 4,000
Therefore the number of Tickets that should be sold
= Number of seats + Number for standing Room
= 240 + 4000
= 4,240 tickets
