my math test is due today :(

The answer would be D

Step-by-step explanation:

It would be D because in order to find the length of the diagonal, you need to use the Pythagorean Theorem, which is a^2+b^2=c^2. In this case it would be 16^2+16^2=c^2 because we don't know the length of the diagonal. To solve this, we need to:

1) Write the formula: 16^2+16^2=c^

2) Square both 16s and add them to get 512

3) then you need to put 512 into a square root like and the simplified version would be 16, but that's not an option, so you simplify it further and you get 22.62, then round up to get 23 feet, or answer D

I hope this helps!!!

i am thinking c. sorry if im wrong .
