Question

If a diagonal of square is 11.3 M approximately what is the perimeter of the square

Answer 1

I got \sqrt(63.845) after doing x squared + x squared since I know squares have four equal sides. From there I made it equal to 11.3 squared and got that as my answer.

Explanation:

Answer 2

A^2+ B^2 = C^2
So
11.3^2 =A^2 +B^2
And
As it is a square
A= B
So
11.3^2 can be halted and then square rooted to get one side
Then times one side by 4
