We do have a pentagon figure with the size equals 25 units.
How to find the area of the figure?
---------------
You can divide it into 5 isoceles triangles, then into 10 right triangles.
The small angle of the right triangles = 360/10 = 36 degs
The short side = 25/2 = 12.5
Use trig to find the 2nd side (the apothem).
--------------
Use the formula
, n = # of sides, s = side length
