What is the length of a diagonal of a square with a side length of 6? A. 3
B. V
C. 3.12
D. 6

8.5? i’m pretty sure

Assuming both the Adjacent and the Opposite side of the triangle is 6, you’ll need to square both the sides and add them.
Step 1. Square both known sides.
6^2+6^2
Step 2. Simplify.
36+36=72
Step 3. Square root your final answer to find the diagonal or hypotenuse.
Square root of 72 is 8.49.

8.5 for the length of the diagonal.

-If one of the sides isn’t 6, repeat the steps above and plug in the different number

Hope i can you!
