Answer 1

The formula to find the area of a regular octagon is:
Area = 2 * (1 + √2) * side length^2

Substitute the side length given:
Area = 2 * (1 + √2) * 14^2
Area = 2 * (1 + √2) * 196
Area = 2 * (1 + √2) * 196
Area = 2 * (1 + √2) * 196
Area = 2 * (1 + 1.41) * 196
Area = 2 * 2.41 * 196
Area = 4.82 * 196
Area = 946.72 cm^2

Therefore, the area of the regular octagon with side length 14 cm is approximately 947 cm^2.

Answer 3

I apologize for the mistake. Let's calculate the area of a regular octagon with a side length of 14 cm again.

To find the area of a regular octagon, we can use the formula:
Area = 2 * (1 + √2) * side length^2

Substitute the side length given:
Area = 2 * (1 + √2) * 14^2
Area = 2 * (1 + √2) * 196
Area = 2 * (1 + 1.41) * 196
Area = 2 * 2.41 * 196
Area = 4.82 * 196
Area = 946.72 cm^2

Therefore, the area of the regular octagon with side length 14 cm is approximately 947 cm^2.
