Answer: OPTION D
Step-by-step explanation:
The missing figure is attached.
According to the data given in the exercise, the scale used is the following:
[tex]5\ cm:\ 8 ft[/tex]
Then, if in the scale drawing the dance floor has a length of 22 centimeters, then its actual length is:
[tex]l=\frac{22\ cm*8\ ft}{5\ cm}\\\\l=35.2\ ft[/tex]
If in the scale drawing the dance floor has a height of 14 centimeters, then its actual height is:
[tex]h=\frac{14\ cm*8\ ft}{5\ cm}\\\\h=22.4\ ft[/tex]
Finally, in order to calculate the area of the actual dance floor, you need to multiply its dimensions.
Therefore, you get that its area is:
[tex]A=(35.2\ ft)(22.4\ ft)\\\\A=788.48\ ft^2[/tex]
