99% of Students Made This Mistake in March 2024 Maths Exam! 😱 | MATH LOGIC

Are you just plugging numbers into the Shoelace Formula? STOP! 🛑 In this video, we analyze why the March 2024 TN Board Exam question on "Area of Quadrilateral" was a massive trap compared to the March 2023 version. What you will learn:The Trap: Why $(-9,-2), (-8,-4), (2,2), (1,-3)$ gives the wrong area if you don't reorder them.The Logic: How a "Self-Intersecting" quadrilateral ruins your calculation.The Solution: The 10-second "Rough Plot" method to ensure your vertices are in the correct anti-clockwise order.Step-by-Step Calculation: Solving both March 2023 and March 2024 problems to secure your 5 Marks.

The Shoelace formula treats this as two triangles with opposite orientations and subtracts their areas, giving you a tiny, incorrect value. To secure your 5 marks, always:Plot a Rough Sketch: Don't guess; take 10 seconds to plot the points on a coordinate axis.Follow the Anti-Clockwise Direction: Pick any point and move counter-clockwise to label them x_1, y_1 to x_4, y_4. This is the only way to ensure the formula gives you the true, positive area.
