    knowing the pentagon has 5 sides, we can draw 5 equilateral triangles within the pentagon, find the area of one triangle, and multiply that area by5

    the length of a side of the pentagon is 2 (tan (108)). we multiply 2 (tan (108)) with the apothem 10.3 then divide by 2 to get the area of 10.3tan (108). multiply this area by 5 to get the answer of 51.5tan (108) = 127.11, rounded to the nearest hundreth
