1. **State the problem:** Find the area of the first parallelogram with base 7 ft and height 3 ft. 2. **Formula:** The area $A$ of a parallelogram is given by $$A = \text{base} \times \text{height}$$ 3. **Apply the formula:** Substitute base = 7 ft and height = 3 ft: $$A = 7 \times 3$$ 4. **Calculate:** $$A = 21$$ 5. **Interpretation:** The area of the parallelogram is 21 square feet. This method applies similarly to other parallelograms by multiplying their base and height.
