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.
The area of a square with 8cm sides is 64
If the square has sides of 8 meters then its area is 8*8 = 64 square meters
64 square inches
4m The apothem is the distance from the center of the shape to the middle of one of the sides. A square of area 64m has sides of 8m (8*8 = 64).
The area of square is : 100.0
Area in square units = 0.5*(apothem)*(perimeter)
For a SQUARE, the area is (2r)2 because the length and width are the same. The apothem (radius) is used to find the area of other regular polygons.
It is approx 2.68 square metres.
a= the square of 7 A equals 28cm
The apothem of a square is equal to one half of the length side of the square. So the side length of the square is 24 (2 x 12). Thus, the area of the square is 576 (24^2).
Area = 10 square feet.
a=\7cm;a=28cm2
The area is 212.1 square feet.
Area = 64*64 = 4096 square m
The area of a regular polygon is equal to one-half the product of the apothem and the perimeter. 40x30 divided by 2=600 square feet
