Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
$\mathrm{I} . A=20 \times B \Rightarrow \frac{1}{2} \times B \times H=20 \times B \Rightarrow H=40$. ∴ I alone gives the answer. II. gives, perimeter of the triangle = 40 cm. This does not give the height of the triangle. ∴ Correct answer is (a).
