A pentagon has 5 sides. The perimeter is 60 so each of its sides is 60/5=12.
Area = n (s/2)^2 / tan( π /n)
= 5(12/2)^2 / tan ( π /5)
= 247.7487

The peremeter of a regular pentagon is 140 inches find the length of each sides?
regular pentagon has five sides,perimeter=140*5=700cm
How do you find the perimeter of a pentagon?
A pentagon, which is a 5-sided figure, will have a perimeter equal to the sum of the lengths of all the sides. This will be true for any polygon; the perimeter of any polygon is the sum of the lengths of all the sides. If the pentagon is a regular pentagon, then the perimeter will be 5 times the length of one of the sides. For any regular polygon, the perimeter will be the length of one side times the number of sides in that polygon.
What is the Perimeter of a regular polygon?
The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.
How do you find the perimeter of a regular pentagon if you know the length of one side?
Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.
What is the formula for finding the perimeter of a pentagon?
The perimeter is the sum of the sides of a polygon. So, to find the perimeter of a pentagon, you need only to add up the 5 side lengths. In the event the pentagon is regular (all equal sides and angles) then you can multiply the measure of the side by 5 to get the perimeter.
How do you find the perimeter of a regular polygon with the apothem and area?
Perimeter = 2*Area/Apothem.
Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m?
Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m.
Find the apothem of a regular polygon with an area of 625 meters and a perimeter of 100?
The apothem is 12.5 metres.
How do you find the volume of a pentagonial prism?
Volume is Area of the Base times the Height of the Prism. To find the area of a Regular Pentagon, you use the formula (1/2)*Perimeter*Length of Apothem.
How do you find the perimeter of a regular pentagon?
measure the sides
What is the area of a regular octagon with a side of 6.5 and an apothem 5?
130 to find the area of any regular polygon, multiply the perimeter by one-half the apothem. This is the same as multiplying the side-lengths by the number of sides by one-half the apothem.
What is the formula to find the perimeter of a regular pentagon with sides 4 cm long?
The formula for the perimeter of ANY regular pentagon isPerimeter = 5 x (length of one side)
What is the Equation for volume of a pentagon?
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.
A regular octagon with sides of length 11 and an apothem of length 8.85 has an area of what?
An apothem of a regular polygon is a segment from its center to the midpoint of a side. You can use the apothem to find the area of a regular polygon using this formula: A = pa/2 where p is the perimeter of the figure and a is the apothem. For a regular octagon with side length 11, the perimeter p = 8(11) = 88. So the area would be A = 88(8.85)/2 = 389.4 square units.

How do you find an apothem?
The formula for finding an apothem is s = 1/2 aP. S is the area, a is the apothem, and P is the perimeter.
