The height of the ladder is 14.491 feet

Explanation:

Given the height is 11 feet

Base = 7 + 2 = 9 feet

Consider the ladder to be the hypotenuse

Applying Pythagoras Theorem,

$H^2 = P^2 + B^2$

Substituting the values in the above formula,

$H^2$ = 112 + 92

$H^2$ = 121 + 81

$H^2$ = 210

H = sqrt(210)

H = 14.491

Therefore, the height of the ladder is 14.491 feet
