A = s2 * 1.72
180° (n - 2), where n is the number of sides.
Any 5 sided polygon is a pentagon. There is no formula for it. We have formulas for area and perimeter. Perhaps that is what you are asking?
add all of the triangle area in a pentagon to get areaThe area A of a regular polygon with n sides each s units long, perimeter p, and apothem a:A = (ans)/2 or A = (ap)/2.
That depends on the size of the pentagon, and whether it is regular or not. In general, you can divide the pentagon into three triangles, and calculate the area of each triangle separately.
Basically, the same as the volume of any other pyramid: the volume is (1/3) x base x height. The "base" refers to the area of the base; for instance, if the base is a regular pentagon, use the formula for a regular pentagon.
180° (n - 2), where n is the number of sides.
To find the area of a pentagon when you have a base height and a length, you can divide the pentagon into simpler shapes, such as triangles and rectangles. If you know the base length and the height from the base to the top vertex, you can use the formula for the area of the pentagon: Area = (Perimeter × Apothem) / 2, or apply the formula for the area of individual shapes you've divided it into. If the pentagon is regular, you can also use the formula for the area of a regular pentagon: Area = (1/2) × Perimeter × Apothem.

dim dim
The formula is 1/2 (apothem) (perimeter)
It is a plane area enclosed by five straight lines.
base times height
Area in square units = 0.5*base*height
the surface area formula is difficult to understand. there is another way to do it.you find the area of one pentagon. then u multiply it by the number of faces which is 12.
To find the area of a regular pentagon, you can use the formula area is equal to n multiplied by r raised to the second power time tan pi/n, where n is the number of sides or 5 and r is the radius. Using the formula, the area is 232.33 square meters.
A pentagon is a 2-D shape. You can't find the volume of it unless it's 3-D. The formula for the area of a pentagon has something to do with the perimeter, the number of sides, the apothem, and the number 2.
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.

No.
Pentagon
The perimeter of a pentagon is the sum of its 5 sides
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).
http://www.mathopenref.com/polygonregulararea.HTML will help you. that's only regular, though. Then, you can multiply the height with the area.
To find the area of a regular pentagon, you can use the formula: ( \text{Area} = \frac{1}{4} \sqrt{5(5 + 2\sqrt{5})} s^2 ), where ( s ) is the length of a side. For a 10'x10' pentagon, you first need to determine the length of one side. In a regular pentagon, the side length can be derived from the geometric dimensions, but typically, a pentagon with a 10-foot perimeter would have a side length of 10/5 = 2 feet. Plugging this into the formula gives an area of approximately 6.88 square feet.
You didn't say it was a regular pentagon. For an arbitrary pentagon, you would calculate its area as you would for any polygon: divide it up into triangles, and add up the areas of the triangle. The area of a triangle is 1/2 times the base times the height, the height being the length of the perpendicular dropped to the base from the opposite vertex.
