ANSWER:
7.07 centimeters
Explanation:
We can calculate the distance between the corners by means of the Pythagorean theorem, since if we cross the line, we have a right triangle as a result.
The Pythagorean theorem states the following;
Where a and b are the sides and c would be the distance between the corners, we replace and solve for c, like this:
The distance between both corners is 7.07 centimeters
