Given :

Slide length, Hypotenuse = 13 feet

Length between end of slide and stairs, Base = 7 feet

Now, perpendicular = ?

By phythogoras theorem,

H² = P² + B²

13² = P² + 7²

P² = 169 - 49

P² = 120

Taking square root of both sides, we get

P = 10.95

Now, according to question stairs extend 2 feet higher than the end of the slide.

So, (10.95 + 2) feet = 12.95 feet
