Area Question in PSLE 2025: Must-Know Concept to Solve Closest Triangle Problem

After the PSLE Mathematics exam, some students recalled specific questions and wanted to check their answers for an Area Question in PSLE 2025. One such question involved the area of a triangle:

Area Question in PSLE 2025

“Refer to the diagram as attached. IF there was a triangle drawn from the points A, B, C or D, to the base, which of the following points will have an area of triangle closest to the shaded part?”

Understand the Area question in PSLE 2025 Mathematics paper. Apply the area formula with confidence and get instant homework help to boost learning.

While this question was not exceptionally difficult, it required clear understanding and correct application of the area formula, Area = ¹/₂ × base × height. Identifying the height correctly was key, especially in a real exam environment where quick, accurate thinking matters.

Self-motivated learners who revisit questions after the exam strengthen their conceptual understanding and build confidence in applying mathematics correctly. Platforms offering online learning and on-demand homework help allow students to discuss their solutions with mentors, receive instant clarification and confirm whether their approach was accurate.

  • Can help me with this question?
  • Cher, what’s ur answer for this question
  • Was in the psle paper I did earlier
  • Hello
  • Let me take a look at the question first. 
  • The base is the black line you drew in the diagram? 
  • Yesh
  • Ok. Let's break down this question step-by-step
  • The area of the shaded part is 5 squares. Assuming the dimensions of each small square is 1 cm²
  • What is the total area of the shaded part? 
  • 5?
  • Yes, you are correct!
  • From your diagram, you can see that if I were to draw a triangle from the base to point A, B, C and D, they have the same base. 
  • So the only difference would be the "height" of the triangles
  • Let's look through the points one by one. 
    A is less than 4. Let it be 3.5. 
    B is more than 4. Let it be 4.5.
    C is 4
    D is 3

    Using the formula for the area of triangles, 1/2 x base x height
    For triangle A: 1/2 x 1 x 3.5 = 1.75
    B: 1/2 x 1 x 4.5 = 2.25
    C: 1/2 x 1 x 4 = 2
    D: 1/2 x 1 x 3 = 1.5 





  • Can you understand my workings?
  • Yes I get it
  • So the answer is B?
  • Yes, you are right!
  • Thank you!
