Answer:
24.33\ ft

Explanation:

You need to draw a Right triangle as the one attached, where "x" is the lenght of a ladder Andrew will need to reach the top and be out of the flower bed.

You must apply the Pythagorean Theorem. This is:


a^2=b^2+c^2

Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.

If you solve for "a", you get:


a=√(b^2+c^2)

In this case, you can identify in the figure that:


a=x\\\\b=24\ ft\\\\c=4\ ft

Therefore, knowing those values, you can substitute them into
a=√(b^2+c^2) and then you must evaluate, in order to find the value of "x".

This is:


x=√((24\ ft)^2+(4\ ft)^2)\\\\x=24.33 ft
