campbell_st · Answer

just take the square root of the area. That will give the side length

remember is a square side length l

$$Area = l^2$$

so if you know the area 

$$595 = l^2$$

hope it helps

okay so do i divide 595 by the sq root?

@campbell_st ?

campbell_st · Answer

no you take the square root... 

as an example 

$$\sqrt{16} = 4 $$

oh okay thats what i ment
THANKS

c?

campbell_st · Answer

I think so... 25^2 = 625... so its between 24 and 25

anonymous · Answer

wait if there are four sides would i have to separate 595 into four

campbell_st · Answer

no... in a square every side is the same length... so area is 

Area = length x length   

or 

A = l^2

so take the square root of the area to get the side length

you answer is correct
