To find the area and perimeter of a rectangle with dimensions 7 and 14, use the following formulas:
-
Area: The area \( A \) of a rectangle is calculated by multiplying its length and width: \[ A = \text{length} \times \text{width} = 7 \times 14 = 98 \] So, the area is 98 square units.
-
Perimeter: The perimeter \( P \) of a rectangle is calculated by adding together all the sides, or using the formula: \[ P = 2 \times (\text{length} + \text{width}) = 2 \times (7 + 14) = 2 \times 21 = 42 \] So, the perimeter is 42 units.
In summary:
- Area = 98 square units
- Perimeter = 42 units
