How high up the wall will a seven meter ladder touch if the foot of the ladder is placed 2 meters from the wall?
The Pythagorean Theorem is: c^2 = a^2 + b^2. So, x = sqrt(77) = 8.77 meters (approximately). Conclusion: The height reached by the ladder is 8.77 meters (approximately).

What is the maximum safe reaching height of an extension ladder?
A person’s maximum safe reaching height is approximately 4′ higher than the height of the ladder. For example, a typical person can safely reach an 8′ ceiling on a 4′ ladder*. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line.
