An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?

Answer 1

9514 1404 393

Answer:

2709.7 square inches

Explanation:

If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.

larger area = 49(55.3 in^2) = 2709.7 in^2
