Area = 10 square feet.
10 square feet
Area of regular polygon: 0.5*2*10 = 10 square feet
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.
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).
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).
the square root of 64 =8/2=4
The apothem and side length are not consistent. That is, a decagon with an apothem of 3.8 cm cannot have a side length of 2.5 cm.If the apothem is 3.8 cm then area = 46.9 cm2 whileif the side length is 2.5 cm then area = 48.1 cm2.The two answers agree at the tens place and so the most accurate answer is 50 cm2 to the nearest 10.
a=\7cm;a=28cm2
