The are of a square is $A=a^{2}$ so 9 root 2 is $9\sqrt{2}$ since the formula says that a need to be squared so we need to square 9 root 2 $(9\sqrt{2})^{2}$ which would be $162$ or another way would be to turn 9 root 2 into a decimal $9\sqrt{2} = 12.727292206...$ then you would square that number just like we did in the first example $(12.7272206)^{2}$ which would give you $161.98$ then all you have to do is round to the nearest tent then you would get $162$ as an answer

i would agree that this step requires to much work so just stick with the first way to do it.

thank you for waiting for this answers i hope it helps a lot i went into details to make sure that you understand if you still don't get it just post another question ill be more than happy to help you out.

The diagram below is made of smaller, identical pieces. Tell how many pieces you would shade to model the given percent.

You would need to shade 1.5 boxes or 6 pieces to have shaded 25% of the shape.

In total, there are 6 boxes. There are 4 pieces per box. In total, there are 24 pieces.

6/4 = 1.5
24/4 = 6

You would need to shade 1.5 boxes, which is equal to 6 pieces or triangles.
