A perimeter of EFGH is 100cm.what is the length of side FE?

I still dont understand give me the answer

What kind of class is "Johnson"? Your question looks like math of some sort. If so, the question seems to be incomplete.

if EFGH is a square, then there are 4 equal sides. Can you do it now?

The perimeter of a square EFGH is 100cm we are looking for length of side

To find the length of side FE, we need some additional information or measurements of the shape EFGH. The given information about the perimeter of EFGH being 100 cm is insufficient to determine the length of side FE on its own.

The perimeter of a shape is the sum of the lengths of all its sides. If we have the lengths of the other sides of EFGH, we can subtract those lengths from the total perimeter to find the length of side FE.

If you have any other measurements or information about the shape EFGH, please provide them, and I would be happy to assist you further in finding the length of side FE.
