The formula for finding the area of a regular pentagon is:
A= 1/4*{sqrt[5(5+2sqrt(5)]}*a^2 where * means multiply, ^2 means 't the power of 2 or squared)
You only need the length of the side.
So the area of this pentagon is given by
A= 1/4{sqrt[5(5+2sqrt(5)]}*.9^2
=1/4*(6.8819)*0.81
= 1.3936 sq mm.
What is the area of a regular pentagon with side length of 9.4 feet and an apothem length of 6.5 feet
The answer is 171.275*apex*

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).
V = (1/3) (area of the base) (height) Area of a pentagon = 1/2 x apothem length x 5 x length of a side of the pentagonthe apothem is the perpendicular distance from the center of the pentagon to the side of the pentagon
regular pentagon area of 12 000 m2 and an apothem of 40 m regular pentagon area of 12 000 m2 and an apothem of 40 m need to figure it out from area 12000 m2
it aould be 10.8 divided by five ok

A regular pentagon with a radius (apothem) of 5.1 units cannot have sides of 7.5 units and, conversely, a regular pentagon with sides of length 7.5 units cannot have a radius of 5.1 units. The figure is, therefore, impossible.
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).

V = (1/3) (area of the base) (height) Area of a pentagon = 1/2 x apothem length x 5 x length of a side of the pentagonthe apothem is the perpendicular distance from the center of the pentagon to the side of the pentagon
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
Area in square units = 0.5*(apothem)*(perimeter)
