Determine the length of the base of a triangle if the height is 15.5 inches and the area is 525 square inches? Round the answer to 3 significant digits.

Using the formula for the area of a triangle, we have:

Area = (1/2) * base * height
525 = (1/2) * base * 15.5
1050 = base * 15.5
base = 1050 / 15.5
base ≈ 67.742 inches

Rounded to 3 significant digits, the length of the base of the triangle is approximately 67.7 inches.
