x= length of the side, in feet
area=x%2Ax=x%5E2=324
x=sqrt%28324%29=18
So the side measures highlight%2818feet%29
How do you find the square root?
There are many ways.
1)You can use a calculator that has a square root key.
2)You can try different numbers:
20%2A20=20%5E2=400 and 324 is less that that, so you know that x is less than 20 .
15%2A15=225 and 324 is more that that, so you know that x is more than 15 .
17%2A17=289 and 324 is more that that, so you know that x is more than 15 .
If you then calculate 18%2A18 you realize that 18%2A18=18%5E2=324 so 18 is the answer.
3)you could factor 324
324=2%2A162 and 162=2%2A81%7D%7D+so+%7B%7B%7B324=2%2A2%2A81
Since you know that 81=9%2A9 324=2%2A2%2A9%2A9=%282%2A9%29%2A%282%2A9%29=18%2A18=18%5E2

square garden
A = Lw = 324ft^2
sqrt%28324ft%5E2%29 = 18ft, length of each side of the Square
