Answer: 9.2 meters
Step-by-step explanation:
Hi, since the situation forms a 2 right triangles (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse (x) of each triangle (in this case the distance between the opposite corners) and a and b are the other sides.
Replacing with the values given:
c^2 = 6^2 + 7^2
c^2 = 36+49
c^2 = 85
c = √85
c = 9.2 meters
