1. The problem is to find the area and perimeter of a given shape. 2. The formulas for a rectangle are: - Area: $$A = l \times w$$ where $l$ is length and $w$ is width. - Perimeter: $$P = 2(l + w)$$ 3. To calculate, substitute the given length and width values into the formulas. 4. Multiply length by width to get the area. 5. Add length and width, then multiply by 2 to get the perimeter. 6. These formulas apply to rectangles; for other shapes, different formulas are used.
