Answer: 14.142
Explanation: What happens when you cut a square diagnally? You get a triangle. What’s the diagonal value? We don’t know. This is like Pythagorean theorem where we solve using a squared + b squared = c squared. Since it’s a perfect square, you put in 10 values for a and b and solve for c. What you get from finishing the formula is 14.142. Correct me if I’m wrong btw.
Hope this helps!!!
