Question 227424
The area for a square is:
{{{L*W=A}}}
Since L and W are the same, call it a side (S):
{{{S^2=A}}}
So, plug in our area:
{{{S^2=900}}}
Take the square root of 900:
{{{S=30}}}, which is the length of the side
To find how much fencing, add up all 4 sides:
{{{S+S+S+S=P}}}
{{{4S=P}}}
{{{4*30=P}}}
{{{120=P}}}, which is our total fencing needed.
