Question

Find the area of a square with diagonals of length 9root2​

Answer 1

Answer:

$A=162$

Step-by-step explanation:

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.
