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

igomit [66]

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.

What property is 5+0=n

andre [41]

Assuming that you mean to put n instead of 5, this is demonstrating The Identity Property.

The identity property is the property that states that by adding 0 to a number, you don't change the value. For example, 510 + 0 = 510.
