Answer:
900
Step-by-step explanation:
5 people are said to occupy a 1000square feet space 
That means we have to look out for how many 1000 square feets are in 180000
That would be 180000/1000 = 180
But 1000 square occupies 5 persons and there are 180 1000square which can occupy 5 people in 180 000 square.
Hence 180 × 5= 900 is the number of persons that the hall can occupy.

F(19)= (3/(19+2)) - sqrt(19-3)
= (3/21) - sqrt(16)
= (1/7) - 4
= (1/7) - (28/7)
= -27/7
= - 3 6/7
