Area of Pentagon
Solution: Since the perimeter is 12, hence
S = 12 + 5 = 2.4 inches
Area:
apothem = tan ((2-2)
2.4
= 2/+tan (T(5-²))
a =
a = (1.2) tan
a = 1.6517 inches
a =
a = (1) tan

Area of Hexagon
Solution: Since the perimeter is 12, hence
S = 12 + 6 = 2 inches
Area:
apothem = tan ((n=2))
= ²tan ((6-2))
4πT
a = tan
a = √3 inches
A = san =

P(a)
2
A = (2.4)(1.6517) (5)
A = 9.9102 sq. inches
A =
apothem
= 1/san
A = ²(2)(√3)(6)
A = 10.3923 sq. inches
