if the square has a perimeter of 80, what is the length of one side?

anonymous · Answer

I have no clue.. it doesnt show its just a problem with no picture or extra info.

nikato · Answer

i know. but you should be able to find it
if all sides of a square are equal and there are four sides
let x be the length of the side
so
x+x+x+x=80
can you find x?

So.. if theres 4 "x's" would they each be 20? since 20x4=80 ?

nikato · Answer

so you have
