Area (Rectangle) to Missing Coordinate - Positive Only (Level 1)

This math topic involves solving problems related to finding missing coordinates of rectangles plotted on a Cartesian grid, based solely on their areas. All problems present rectangles with positive coordinate values and ask the learner to determine missing x or y coordinates when the area of the rectangle is given. The student is provided with multiple choices for each query, enhancing their skills in geometry, spatial reasoning, and algebraic manipulation involving rectangular area calculations in a graphical coordinate context.
