Question

* Required If each person occupies 2.5 square feet, how many people would fill up an arena with standing room only that had a width of 1100 feet and a length of 2500 feet? 0 1,100,000 people O 6,875,000 people O 2,750,000 people 0 2,500,000 people​

Answer 1

Length and width of arena are 2500 ft and 1100 ft.

Area required by each person , a = 2.5 ft².

Now, area of arena is :

$A=1100\times 2500\ ft^2\\\\A=2.75\times 10^{6}\ ft^2$

Now , number of people can fit is :

$n =\dfrac{A}{a}\\\\n=\dfrac{2.75\times 10^{6}}{2.5}\\\\n=1,100,000$

Hence, this is the required solution.
