Final answer:
The length of the wall is 49 feet.
Step-by-step explanation:
To find the length of the wall, we need to divide the area of the wall by its height. The area of the wall is given as 882 square feet, and the height is 18 feet. We can use the formula for the area of a rectangle, which is length multiplied by width. Rearranging the formula, we can solve for the length by dividing the area by the height: length = area / height. Substituting the given values, we have length = 882 / 18 = 49 feet.
