In the context of SSC CGL Mensuration 2D, this topic focuses on flat figures such as triangles, squares, circles, rectangles, and other polygons that lie entirely on a plane and have only length and breadth, no height or depth.</p>    <p>In the <a href="https://ssc.gov.in/home/notice-board">SSC CGL</a> exams, Mensuration 2D plays a significant role in testing a candidate’s ability to apply geometric formulas, visualize shapes, and solve practical problems based on daily life applications like finding the length of fencing around a garden, the cost of painting a wall, or the area of a shaded region. Candidates are expected to calculate values such as area, perimeter, diagonals, and side lengths using well-defined mathematical expressions.</p>    <p>The SSC CGL Mensuration 2D questions may be framed as direct formula-based problems or as application-based word problems. These are generally moderate in difficulty but highly scoring with proper preparation. A strong understanding of Mensuration 2D also supports performance in advanced geometry and coordinate geometry questions, particularly in Tier 2.
