The area of a pentagon of side length t is given by the formula t2 (sqrt 25 + 10 (sqrt 5)) / 4, or 5t2 tan (54o) / 4. In this case, a pentagon with one side of 10cm has an area of 102 (sqrt 25 + 10 (sqrt 5)) / 4 = 172.05 cm2 (accurate to two decimal places).

What is the area of a regular pentagon if one side is 20?
Area of a regular pentagon with a known side S can be closely approximated by formula 5S2/4 tan 36. Taking 4 tan 36 as 2.906 then the area sought is 2000/2.906 ie 688.23 sq units.
What is the perimeter of a regular pentagon with side lengths of 5 centimeters?
A pentagon has 5 sides. A regular pentagon has sides of all the same length. So a regular pentagon of side 5cm has a perimeter of 5 x 5cm = 25cm.
What is the perimeter of a regular pentagon with 9cm sides?
Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
Write an expression for the perimeter of a pentagon?
P = 5s, where s is the length of a side. This applies to a regular pentagon. If the pentagon is irregular then P = (s1 + s2 + s3 + s4 + s5)

How to Calculate an irregular pentagon area?
To calculate the area of an irregular pentagon, you can divide it into shapes with known formulas (such as triangles and rectangles) and then sum their areas. Alternatively, you can use a formula specifically designed for irregular pentagons, such as Heron's formula if you know all the side lengths. You may also use trigonometry to calculate the area if you know certain angles and side lengths within the pentagon.
How do you calculate the area of an pentagonWhy?
The area (A) formula of a regular pentagon of side length (a) is: A = [a2x(25+10x51/2)1/2]/4 See the why in the development of such formula in the weblink below.

What is the area of a regular pentagon with a side length of ten units?
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).
What is the area of a regular pentagon if one side is 20?
Area of a regular pentagon with a known side S can be closely approximated by formula 5S2/4 tan 36. Taking 4 tan 36 as 2.906 then the area sought is 2000/2.906 ie 688.23 sq units.
How do you get 26.8 for the perimeter of a pentagon?
If a pentagon, which is a 5-sided figure, has 26.8 for a perimeter, then each side of that regular pentagon is 26.8 divided by 5 = 5.36 long. How do you get 26.8 for the perimeter of a regular pentagon? Use a regular pentagon with 5.36 for a side length.
