The formula to calculate the Length of Rectangle (l) is:
\[ l = \frac{P - 2b}{2} \]
Where:
The Length of Rectangle is any one of the pair of parallel sides which are longer than the remaining pair of parallel sides.
Perimeter of Rectangle is the total length of all the boundary lines of the Rectangle.
Breadth of Rectangle is any one of the pair of parallel sides which are shorter than the remaining pair of parallel sides.
Let's assume the following values:
Using the formula:
\[ l = \frac{28 - 2 \cdot 6}{2} \]
Evaluating:
\[ l = 8 \]
The Length of Rectangle is 8 Meters.
| Perimeter (P) (Meters) | Breadth (b) (Meters) | Length (l) (Meters) |
|---|---|---|
| 20 | 4 | 6.00 |
| 20 | 6 | 4.00 |
| 20 | 8 | 2.00 |
| 28 | 4 | 10.00 |
| 28 | 6 | 8.00 |
| 28 | 8 | 6.00 |
| 36 | 4 | 14.00 |
| 36 | 6 | 12.00 |
| 36 | 8 | 10.00 |
