Answer:

30cm^2

Explanation:

The apothem is a line segment from the center to the midpoint of one of its sides. You can first divide the octagon into

8

small triangles. Each triangle has an area of

2.5 cm

2x 3 cm =3.75 cm2 then 3.75 cm 2×8=30cm2 is s the total area of the octagon.

Hope you understand. If not, please tell me.
