Answer 1

Answer:

Step-by-step explanation:

No of people in hall=Area of hall/Area taken by person

---->   (23*20)/6

--->   460/6

= 76.6666666666667

Answer 2

Step-by-step explanation:

l = 23m

b = 20m

h = 12m

According to the question

TSA - LSA

2(lb + bh + hl) - 2(l+b) h

2(460 + 240+ 276) - 2(43)12

2(976) - 2(516)

1952 - 1032

= 960m^2

1 person = 6m^2

then, Total no. persons = 960/6

= 153 persons..
