Mensuration Questions for SSC CHSL, Download Free PDF

Planning for the SSC CHSL Tier 1 exam? You know the Quantitative Aptitude section is where you can secure easy, high-scoring marks, and Mensuration is important. You can expect at least 2 to 3 direct, formula-based questions from Mensuration in the CHSL exam. I have personally analyzed many previous year question papers and found that mensuration questions are pure formula checks. If you know the formula for the volume of a sphere or the area of a trapezoid, you can solve them easily. In this blog, we’ve provided exam-level Mensuration questions for the SSC CHSL exam in a PDF that you can download for free. But before you download it, take a few free Mensuration tests to analyze your understanding of this topic.

Concept of Mensuration for SSC CHSL

Mensuration is simply the branch of geometry that deals with the measurement of length, area, and volume of different shapes. For the SSC CHSL exam, the topic is divided into two main parts:

1. 2D Mensuration (Area and Perimeter): Deals with flat shapes like squares, rectangles, triangles, circles, and parallelograms.
2. 3D Mensuration (Volume and Surface Area): Deals with solid objects like cubes, cuboids, cylinders, cones, and spheres.

Formulas of Mensuration For 2D Shapes:

Rectangle:

• Area of Rectangle = Length × Breadth.
• Perimeter of a Rectangle = 2 × (Length + Breadth)
• Length of the Diagonal = √(Length² + Breadth²)

Square:

• Area of a Square = Length × Length = (Length)² 
• Perimeter of a square = 4 × Length
• Length of the Diagonal = √2 × Length

Parallelogram:

• Area of a Parallelogram = Length × Height
• Perimeter of a Parallelogram = 2 × (Length + Breadth)

Triangle:

• Area of a triangle=(1/2)(Base × Height)

For a triangle with sides measuring a, b and c, respectively:

• Perimeter = a + b + c
• s = semi perimeter = perimeter/2 =  (a+b+c)/2
• Area of Triangle,

Trapezium:

• Area of a trapezium = (1/2) × (sum of parallel sides) × (distance between parallel sides)
  = (1/2) × (AB+DC) × AE
• Perimeter of a Trapezium = Sum of All Sides

Rhombus:

• Area of a rhombus=(1/2)×Product of diagonals
• Perimeter of a rhombus = 4 × l

Preparation Tips for SSC CHSL Mensuration Questions

Mensuration is an easy score-maker if you follow a dedicated strategy. These tips will help you maximize your problem-solving skills for this topic:

1. Create a Formula Chart: Dedicate one single page to write down every single 2D and 3D formula. Revise this chart every day for instant recall.
2. Use Pythagoras Triples: Memorize common Pythagorean triplets (e.g., 3-4-5, 5-12-13, 8-15-17). These are often used to find missing dimensions (height, diagonal) quickly without complex calculations.
3. Practice Conversion: Be careful with units! Practice converting between meters and centimeters, and between area (cm²) and volume (cm³).
4. Know the Ratio Rules: Memorize rules like: if the side ratio is a:b, the area ratio is a²:b², and the volume ratio is a³:b³. This saves huge calculation time.
5. Solve High Volume: Mensuration requires high repetition. Solve a dedicated set of 25 questions daily using our free topic tests to solidify your formula application.
