Question

21. SCALE FACTOR A regular nonagon has an area of 90 square feet. A similar

nonagon has an area of 25 square feet. What is the ratio of the perimeters of
the first nonagon to the second?

Answer 1

The ratio of the perimeters of the first nonagon to the second is 3.6 to 1.

Explanation:

Given that a regular nonagon has an area of 90 square feet, and a similar nonagon has an area of 25 square feet, to determine what is the ratio of the perimeters of the first nonagon to the second, the following calculation must be performed:

25 = 1

90 = X

90/25 = X

3.6 = X

Therefore, the ratio of the perimeters of the first nonagon to the second is 3.6 to 1.
