Cartesian Grid - Area (Rectangle) to Missing Coordinate - Including Negative (Level 1)

This math topic focuses on utilizing the Cartesian grid to solve geometry problems involving rectangles. The main skill practiced is finding missing coordinates given the area of the rectangle, which may require understanding and applying the formula for the area of a rectangle. The problems incorporate negative coordinates, enhancing students' ability to work within the full scope of the Cartesian plane. Each question provides multiple choices for the potential solution to the calculation of the missing value, reinforcing logical thinking and application of area calculations in a coordinate geometry context.
