not at all

Ok, here is the formula for the area of a square.
Remember that a square is a rectangle that has all sides of equal length.
For a rectangle, the area is
A = LW
You remember that?

mathstudent55 · Answer

In a square, the formula is similar, but since the length and width are the same, you can call the length of all sides s, and then the area of a square is
A = s^2

mathstudent55 · Answer

Using the formula for the area of the square, we can find the length of the side, since we are given the area.

$A = s^2$

$200 = s^2$

$s^2 = 200$

$\sqrt{s^2} = \sqrt{200} $

$s = \sqrt{200} $

Now we know that a square that has area of 200 m^2 has a side of $\sqrt{200}$ m.

Now we can do the next step which is to find the length of the diagonal.
For this we need to use the Pythagoras theorem.
