    Area of a triangle: TEAS Practice Question with Answer & Explanation

    An original TEAS 7-style math practice question, written for nursing-school applicants — with a full breakdown of every answer choice.

    Question

    What is the area of a triangle with base 12 cm and height 5 cm?

    • A.17 cm²
    • B.30 cm²
      Correct
    • C.60 cm²
    • D.120 cm²

    Correct answer: B. Area = 1/2 × base × height = 1/2 × 12 × 5 = 30 cm².

    Why B is correct

    Area = 1/2 × base × height = 1/2 × 12 × 5 = 30 cm².

    TEAS skill review

    This question tests area of a triangle, a concept that can appear in the TEAS math section. Read the prompt carefully, identify the rule or evidence being tested, and eliminate options that do not directly satisfy it.

    Why the other choices are incorrect

    The remaining choices conflict with the relevant fact, calculation, language convention, or passage evidence. Check every option against the exact wording of the question rather than choosing an answer that is only generally related to the topic.

    Quick study tip: A triangle has half the area of a matching rectangle.
