1. Let's start by stating the problem: We know Tina's office area is 8.2 m². 2. Bill's office area is 7100 cm² larger than Tina's office. 3. First, we need to convert 7100 cm² to m² since 1 m² = 10,000 cm². $$\text{Increase in m}^2 = \frac{7100}{10000} = 0.71\text{ m}^2$$ 4. Now, add this increase to Tina's office area to find Bill's office area. $$\text{Bill's area} = 8.2 + 0.71 = 8.91\text{ m}^2$$ 5. Therefore, the area of Bill's office is **8.91 m²**.
