To calculate the perimeter of a rectangular garden, use the formula:

$\text{Perimeter} = 2 \times (\text{Length} + \text{Width})$

Given:

• Length = 15 meters
• Width = 10 meters

Substitute the values into the formula:

$\text{Perimeter} = 2 \times (15 + 10) = 2 \times 25 = 50 \, \text{meters}$

So, the perimeter of the garden is 50 meters.

2. What is the perimeter if the length increases by 5 meters?
3. How would the perimeter change if the shape was a square with the same area?
4. How does the perimeter of a triangle compare to that of a rectangle with similar side lengths?

Tip: Always double-check whether you're solving for perimeter (sum of sides) or area (space inside) when dealing with shapes.
