To find the length of the ladder, we can use the Pythagorean theorem. The ladder forms a right triangle with the wall and the ground, where:
- One leg is the height up the wall (48 feet),
- The other leg is the distance from the bottom of the ladder to the wall (20 feet),
- The hypotenuse is the length of the ladder (which we want to find).
According to the Pythagorean theorem:
\[
c^2 = a^2 + b^2
\]
where \(c\) is the length of the ladder, \(a\) is the height (48 feet), and \(b\) is the distance from the wall (20 feet).
Plugging the values into the formula:
\[
c^2 = 48^2 + 20^2
\]
Calculating \(48^2\) and \(20^2\):
\[
48^2 = 2304
\]
\[
20^2 = 400
\]
Now, add those two values:
\[
c^2 = 2304 + 400 = 2704
\]
To find \(c\), take the square root:
\[
c = \sqrt{2704} = 52
\]
So, the length of the ladder is **52 feet**.
