A parallelogram has an area of 128 square meters, and its height is double the length of the base. What is the length of the base?
Explanation
Given the area (A) = 128 sq m and height (h) = 2 × base (b), the area formula is A = b × h = b × 2b = 2b². So, 2b² = 128, which gives b² = 64. Therefore, b = 8 meters.
