The area of a decagon with a side of 4m is 123.1m2
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.
4m2
378 cm ^2
The area of rectangle is : 20.0
a decagon
6m and one side is 4m what isthe length of the other side
41.57cm2
The area of 4m by 4m is 16 square meters.
5xy
To find the area of a square, you simply multiply the length of one side by itself. In this case, 4m x 4m equals 16 square meters. This is because each side of the square is 4 meters long, so when you multiply them together, you get the total area in square meters.
decagon
4m because 42 = 16m2
Decagon
The formula for determining the area of a decagon is A = 2.5dt where t is the length of one edge and d is the distance between two parallel sides
A decagon has 10 sides.
The apothem and side length are not consistent.

a decagon has 10 sides- the stem deca- means ten and -gon means side, therefore decagon means a ten-sided object
