Step-by-step explanation:
The area of a regular octagon is given by:
A = (4) * (L) * (ap)
Where,
L: side
ap: apotema
Substituting values we have:
A = (4) * (19) * (16)
A = 1216 square inches
Answer:
The area of a regular octagon with an apothem 16 inches long and a side 19 inches long is:
A = 1216 square inches
The formula for the area of a hexagon is
A=1/2ap
A=1/2 10.4*72
A=1/2*748.8
A=374.4 sq yds
Key
a=apothem
p=perimeter
