To determine the perimeter of a shape, you need to know the lengths of all its sides. The perimeter is calculated by adding up the lengths of these sides.
Let's say you have a regular polygon with n sides, each of length ( s ). The perimeter ( P ) can be calculated using the formula:
[ P = n \times s ]
Solution:
-
Identify the Number of Sides (( n )) and the Length of Each Side (( s ))
- For example, if the polygon is a square, ( n = 4 ).
- If the shape is a regular triangle (equilateral triangle), ( n = 3 ).
-
Plug the Values into the Formula
[ P = n \times s ]
-
Calculate the Perimeter
-
For a square with each side ( 2.25 ) units: [ P = 4 \times 2.25 = 81 \text{ units} ]
-
For an equilateral triangle with each side ( 27 ) units: [ P = 3 \times 27 = 81 \text{ units} ]
-
Final Answer:
[ \boxed{81} ]
