Help!!! Please!! In a hurry!!
A stop sign is a regular octagon. This stop sign has a height of 30 inches and each side is 12.43 inches. The area of a 30-inch sign is ____ in2 to the nearest square inch.

Answer 1

This is as simple as finding the area of a triangle. You have a right triangle from the top of the sign, with side b = 30/2 = 15 inches, and side A = 12.43/2 = 6.215 inches.

Triangle area = 0.5ba = 0.5(15)(6.215) = 46.6125 inches.

Now, you have exactly 2*8 of those triangles, two for each of 8 sides.

The answer is 16*46.6125.
