Afence is 695 m long. it is cut into three parts. two parts are the same length, and the third part is 20 m longer than either of the other two. find the length of each part.

Let the two parts with equal length have length x.
The longer part has length x + 20.

The sum of the three lengths is 695 m.

x + x + x + 20 = 695

3x + 20 = 695

3x = 675

x = 225

x + 20 = 245

The two short parts measure 225 m, and the long part measures 245 m.
