Question

A ladder 7m long leans against a wall .its foot is 2m from the wall.calculate how far from the wall the ladder reaches

Answer 1

Well, I'd say if the foot is 2m from the wall, the ladder reaches 2m from the wall ...

But, since you probably want to know the third side of the triangle,

Use the Pythagorean Theorem
√(7^2 - 2^2) = √45 = 6.7 m
