An acre isn't a unit of length, it is a unit of area. You can have a surface - for example a rectangle - as long or as short as you like, provided the product of the two sides is enough to get a surface of 15 acres, in this case.
Well, honey, if we're talking about a square with sides that are all 3cm long, then each side is, surprise surprise, 3cm in length. It's a square, not a triangle – all sides are equal. So, grab a ruler, measure it out, and you'll see that each side is indeed 3cm.
A polygon with 10 sides is called a decagon. the length of the sides doesn't matter, as long as it has ten sides.

A quadrilateral. If the short sides are equal in length and the long sides are equal in length then it is a kite. Otherwise it could be a trapezium (eg one with sides 4, 5, 16, 13) or it is an irregular quadrilateral.
Individual sides can be of any (positive) length. Also, each of the sides has to be smaller than the sum of the other two sides.
In a rectangle, opposite sides are of equal length. So basically, the two shorter sides are the same length as each other, and the two bigger sides are equal length to each other. However, the short and long sides aren't equal.
A square acre has four sides, each side being 208.71 feet long.

You have to measure how long each side on the shape is.Then you add up all the sides length e.g if you have 4 sides which are 2cm each then you add them together which is 8cm.
Each of the 10 sides of the decagon is 1.9314 inches long.
