Thats simple, a^2 + b^2=c^2. Right? well on a square, thats a right triangle, so a= b. So (a^2 + a ^ 2) = (3* square root of 2)^2 I think you can take it from there as i will not do your homework for you, but set you up pretty nice.

3â2=4.24264 and 4.24264² =18
Therefore as â 9 +9 = 4.24264 the â9 must be length of one side
+3 and x 4 sides =12
