Given:
Octagon-shaped patio
Side length = 24ft
apothem length = 60ft
Area of a regular octagon = 2 * a² * (1 + √2)
a = side length
A = 2 * (24ft)² * (1 + √2)
A = 2 * 576ft² * (1 + 1.414)
A = 2 * 576ft² * 2.414
A = 2,780.93 ft²
1 = 1 x 10 exponent 0
27.5 = 2.75 x 10 exponent 1
43.71, 43.6, 41.92 greatest to least
28 minutes
45 - 11 divided by 2 = 17 + 11 = 28 minutesa
