110.11 square metres
break it into 5 triangles; 4m x 4/tan(72o/2) x 5 triangles
Each side is 2 meters long
Each of the 5 branches of the military has a side of the pentagon.
Each side of the square is 3 meters in length
A regular pentagon has five (5) equilateral triangles within it. Find the area of each triangle (1/2bh where b is the base of the triangle or the length of a side of the pentagon, and h is the height of the triangle or the apothem of the pentagon) and multiply the area of the triangle times five (5).
If 6 is the side of a regular pentagon, the area is 61.937
Each side will be 9.6 meters.
Area = 172.05 cm2
i belive it is 60
Each side is 2 meters long
The side length of a square with an area of 9 square meters would be 3 meters.

== == The question does not make sense because the numbers are not consistent. It is a bit like asking the area of a circle if the radius is 6 and the diameter is 8. A circle's diameter is constrained to be twice the size of the radius. Similarly, the apothem of the specified pentagon is constrained to be a particular size and the apothem size is not 6.Also, a pentagon does not have a radius, so that part of the question does not make sense.Notes: * A previous version of the answer to this question on this site mentioned that the source of the solution is from www.icoachmath.com. However, there does not seem to be any pentagon area problems on that site. * A precise regular pentagon area is defined on the linked site:knol.google.com/k/scot-ellison/area-of-a-regular-pentagon
Each side of the square is 3 meters in length
A square 60 meters on each side will have an area of 3600 square meters.
