Answer:
216 people
Step-by-step explanation:
Given:
2.5 feet² is occupied by 1 person
Dimension of room = 216 in × 360 in
Required:
No. of people that would occupy the room
SOLUTION:
Step 1:
Convert the dimensions of the room from in to ft
Note: 1 foot = 12 inches
216 inches = 
360 inches = 
Step 2: calculate area of the room.
Area of the room = 30*18 = 540 ft²
Step 3: calculate the no. of people the room will contain.
2.5 ft² will contain one person
Therefore, 540 ft² will contain: 
80X3 PLUS 2x3 that is awnser
1 ft = 12 in.
4 ft = 4 * 1 ft = 4 * 12 in. = 48 in.
4 ft 7 in. = 48 in. + 7 in. = 55 in.
4 ft 7 in. < 56 in.
