The total area of the shaded parts of the heptagon is $1 \mathrm{~cm}^{2}$. The area of the original triangle is $1 \frac{1}{2}$ times the area of the heptagon. What is the area of the original triangle, in $\mathrm{cm}^{2}$ ? <image1> You FIRST think about the reasoning process as an internal monologue and then provide the final answer. The reasoning process MUST BE enclosed within <think> </think> tags. Please answer the final answer within the <answer> </answer> tags.
