1. **Problem statement:** The length of a rectangle is 7 cm longer than its width. The perimeter of the rectangle is 74 cm. We need to find the length and the area of the rectangle.
2. **Formula used:** The perimeter $P$ of a rectangle is given by $$P = 2(\text{length} + \text{width})$$
3. **Define variables:** Let the width be $w$ cm. Then the length is $w + 7$ cm.
4. **Set up the equation:** Using the perimeter formula,
$$74 = 2((w + 7) + w)$$
5. **Simplify the equation:**
$$74 = 2(2w + 7)$$
$$74 = 4w + 14$$
6. **Solve for $w$:**
$$4w = 74 - 14$$
$$4w = 60$$
$$w = \frac{60}{4} = 15$$ cm
7. **Find the length:**
$$\text{length} = w + 7 = 15 + 7 = 22$$ cm
8. **Calculate the area:** The area $A$ of a rectangle is
$$A = \text{length} \times \text{width} = 22 \times 15 = 330$$ cm$^2$
**Final answer:** The length is 22 cm and the area is 330 cm$^2$.
