Apply the area and perimeter formulas for rectangles in real world and mathematical problems

What you'll learn

1. Use the area formula A = l x w to find the area of a rectangle when both dimensions are given
2. Use the perimeter formula P = 2l + 2w (or equivalently P = 2(l + w)) to find the perimeter of a rectangle when both dimensions are given
3. Find an unknown dimension of a rectangle given its area and one side length, by viewing the area formula as a multiplication equation with an unknown factor
4. Find an unknown dimension of a rectangle given its perimeter and one side length
5. Determine whether a real-world problem requires area or perimeter based on context clues, and select and apply the correct formula
