Answer :

sqdancefan

Answer:

  7 yards

Step-by-step explanation:

You want the size in yards of a square that will support 150 people with a density of less than 4 per square yard.

Platform size

The area of the platform must be at least ...

  [tex]\dfrac{150\text{ people}}{4\text{ people/yd}^2}=37.5\text{ yd}^2[/tex]

A square with a side length of 6 yards is insufficient.

The next larger square will be one with a side length of 7 yards.

The minimum safe platform size is 7 yards square.
