+ * Difficulty: Easy
+ *
+ * You are given a 2D 0-indexed integer array dimensions.

+ * For all indices i, 0 <= i < dimensions.length, dimensions[i][0] represents the length and
+ * dimensions[i][1] represents the width of the rectangle i.
+ *
+ * Return the area of the rectangle having the longest diagonal. If there are multiple rectangles
+ * with the longest diagonal, return the area of the rectangle having the maximum area.
