Question

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

Answer 1

`A=162`

Explanation:

The are of a square is
`A=a^(2)` so 9 root 2 is
`9√(2)` since the formula says that a need to be squared so we need to square 9 root 2
`(9√(2))^(2)` which would be
`162` or another way would be to turn 9 root 2 into a decimal
`9√(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.
