The 8 sides of the regular octagon are all the same length, so the perimeter of it is 8*(12.4 in) = 99.2 in.

The area of a regular polygon is half the product of the perimeter and the apothem.
  area = (1/2)(99.2 in)(15 in) = 744 in²

The area of the stop sign is 744 in².

Answer:

y = -63

Step-by-step explanation:

y - 15 = -78

Add 15 on both sides to get y alone:

y - 15 + 15 = -78 + 15

y = -63

Find the area of the trapezoid.
ycow [4]
11 in - 7 in = 4 in
a^2 + (4 in)^2 = (5 in)^2
a^2 + 16 in = 25 in
a^2 = 9 in
a = 3 in
7 in x 3 in = 21 in
1/2( 3 in ) ( 4 in ) = 6 in
a = 21 in + 6 in = 27 in
