Question

During the day, Lola's dog is tied by rope to a tree in the center of her yard. The scale drawing below shows the area that the dog has to run. If the actual length of the rope is 12 1/2 feet, what is the scale used in the drawing?

Answer 1

`(1)/(96)`

Explanation:

First convert the feet two inches.

12.5 * 12 = 150 inches.

To find the scale used in the drawing, we divide the radius of the circle in the drawing, by the actual radius.

1
`(9)/(16)\\` / 150 = 1/96

The scale of the drawing is 1/96 of the actual length
