The perimeter of a rectangle is the total distance around the outside of the rectangle. It can be visualized as the fencing that surrounds a park or a backyard.
The formula to calculate the perimeter of a rectangle is:
\[ P = 2 \times (L + W) \]
Where:
To calculate the perimeter of a rectangle, you need to:
For a rectangle with a length of 14 feet and a width of 6 feet:
\[ P = 2 \times (L + W) = 2 \times (14 + 6) = 2 \times 20 = 40 \, \text{feet} \]
Another example: For a rectangle with an area of 35 square feet and a length of 7 feet, find the width and then the perimeter:
\[ \text{Area} = L \times W \Rightarrow W = \frac{\text{Area}}{L} = \frac{35}{7} = 5 \, \text{feet} \] \[ P = 2 \times (7 + 5) = 2 \times 12 = 24 \, \text{feet} \]
