A regular pentagon, a regular hexagon and a square each have sides of 6 cm in length. a. How much longer is the perimeter of the regular hexagon than the perimeter of the square? cm

b. What is the perimeter of the regular pentagon? cm

Correct option is C)

ABCDE is a pentagon. Hence, ∠EDC=108

∘

(Interior angle of a pentagon)

Also, ∠EDF=90

∘

Now, ∠CDF=360

o

−∠EDF−∠EDC

∠CDF=360

o

−90

o

−108

o

=162

o

Now, Interior angle of a polygon,

n

180

o

(n−2)

=162

o

180n−360=162n

18n=360

n=20

Thus, polygon has 20 sides.

easy math just plug in a and b
