Question

A stop sign is in the shape of a regular octagon. A regular octagon can be created using eight triangles of equal area. One triangle that makes up the stop sign has a base of 20 inches and a height of 24 inches. Calculate the area of the stop sign.

Answer 1

the answer is 1,920 inches

Answer 2

`1920 in^2\\`

Explanation

Number of triangle in octagon
`= 8\\`

Area of one triangle
`= (1)/(2) bh\\= (0.5)(20) (24)\\= 240 in^2\\`

Area of eight triangle = Area of Octagon

`= 8 * 240 in^2\\= 1920 in^2\\`
