What is the height of a right-angled triangle? (M.A.T., 2005) I. The area of the right-angled triangle is equal to the area of a rectangle whose breadth is 12 cm. II. The length of the rectangle is 18 cm.
Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
Using both I and II, we have: Area of right-angled triangle = Area of rectangle $=(18 \times 12) \mathrm{cm}^{2}=216 \mathrm{cm}^{2}$. But, we can't find the height of the triangle unless the base is given. Thus,. even both I and II together do not give the answer. ∴ Correct answer is (d).
