Solution: Rectangle Area

Understand how to calculate the combined area of two rectangles on a 2D plane, including cases where they overlap. Learn to compute each rectangle's area and accurately subtract overlapping regions for correct total coverage.

We'll cover the following...

Statement

You are given the coordinates of two axis-aligned rectangles in a 2D plane. Your task is to calculate the total area covered by both rectangles.

  • The first rectangle is specified by the coordinates of its bottom-left corner (ax1, ay1) and top-right corner (ay1, ay2).

  • Similarly, the second rectangle is defined by its bottom-left corner (bx1, by1) and top-right corner (bx2, by2). ...
