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
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.

You cannot have a shaded area of 4m since area cannot be measured in metres.
a decagon has 10 sides- the stem deca- means ten and -gon means side, therefore decagon means a ten-sided object
