.

(1)  The perimeter is 8 times the side length.



(2)  The area is comprised of 8 (eight) isosceles congruent triangles with the common center.


     Find the area of one (of each) such a triangle as half the product the side length by the apothem.


    Then take this area 8 times.

Solved.


===============


Comment from student: so to get the area would it be 4.6*8=36.8?
