Let us substitute:
A =
=
Your answer will be the second option
3 ) We know the value of the apothem to be 16.9 cm and the side length to be 14 cm
The perimeter of this octagon is:
P = 8 x side
= 8 x 14
= 112 cm
Area formula of a regular octagon is
A =
A =
= 946 .4 cm²
Your answer will be the last option
4 ) The apothem of the regular pentagon is given to be 5.5 cm and the side is 8 cm
