Question

Find the area of this regular polygon. (Round to one decimal spot if necessary)

Answer 1

the area of a regular polygon is

A = p x a/2

where p is the perimeter of the polygon,

a is the apothem.

p = sn

n is the number of sides

s is the sides length

p = 6.7 x 7

p = 46.9

therefore,

A = 46.9 x 7/2

A = 328.3/2

A = 164sq.u
