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.
The area of a regular pentagon can be calculated using the formula: ( \text{Area} = \frac{1}{2} \times \text{Perimeter} \times \text{Apothem} ). For a pentagon with a side length of 9 mm, the perimeter is ( 5 \times 9 = 45 ) mm. Using the apothem length of 6.2 mm, the area is ( \frac{1}{2} \times 45 \times 6.2 = 139.5 ) square millimeters. Thus, the area of the pentagon is 139.5 mm².
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*
To find the apothem length ( a ) of a regular pentagon, you can use the formula for the area ( A ) of a pentagon: [ A = \frac{1}{2} \times Perimeter \times Apothem ] The perimeter ( P ) of the pentagon is ( 5 \times \text{side} = 5 \times 8 = 40 ) in. Given the area ( A = 140 ) sq. in., we can rearrange the formula to find the apothem: [ 140 = \frac{1}{2} \times 40 \times a \implies 140 = 20a \implies a = \frac{140}{20} = 7 \text{ in.} ] Thus, the apothem length is 7 inches.

Apothem length: 4.82 35.35 square units APEX
The area ( A ) of a regular pentagon can be calculated using the formula ( A = \frac{1}{2} \times \text{perimeter} \times \text{apothem} ). The perimeter of the pentagon is ( 5 \times 9.4 = 47 ) feet. Thus, the area is ( A = \frac{1}{2} \times 47 \times 6.5 = 152.75 ) square feet.
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
