Tom made a square measuring 8 feet by 8 feet, and had 18 friends stand inside it as if they are watching a band at a small club.
UNO [17]

Answer:

The ratio of this number to the rectangle’s area is 9:32.

Step-by-step explanation:

The information provided are:

  • Tom made a square measuring 8 feet by 8 feet.
  • He had 18 friends stand inside it as if they are watching a band at a small club.

The area of the square is:

<em>A</em> = (side)²

  =(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{2}

The number of people standing insider the square is:

<em>n</em> = 18

Compute the ration of <em>n</em> to <em>A</em> as follows:

n:A=18:64

        =\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32

Thus, the ratio of this number to the rectangle’s area is 9:32.
