1. **Problem statement:** Calculate the perimeter and area of the triangle with sides 12.2 cm, 12.2 cm, and base 14 cm, and height 10 cm. 2. **Formulas:** - Perimeter of triangle: $$P = a + b + c$$ where $a$, $b$, and $c$ are the side lengths. - Area of triangle: $$A = \frac{1}{2} \times \text{base} \times \text{height}$$ 3. **Calculate perimeter:** $$P = 12.2 + 12.2 + 14 = 38.4\text{ cm}$$ 4. **Calculate area:** $$A = \frac{1}{2} \times 14 \times 10 = 7 \times 10 = 70\text{ cm}^2$$ 5. **Answer:** - Perimeter = 38.4 cm - Area = 70 cm²
