Question

.

Answer 1

\[c^2 = a^2 + b^2\]
where c is the length of the hypotenuse
a and b are the length of the legs
---------------------------------
having x as the variable representing a and b and c is 12 yds you'll have:
\[12^2 = x^2 + x^2\]
\[144 = 2x^2\]
Divide the whole equation by 2
\[72 = x^2\]
Get the square root
\[x = \sqrt72\]
\[x = \sqrt {36(2)}\]
\[x = 6 \sqrt 2\]
----------------------------------
Area of square:
\[A = s^2\]
where s is the length of the side
