I am still confused..please help.

Dawn or Krystin -- whoever you are -- what confuses you?

The perimeter of an object is the distance around it.

Finding the perimeter of a two-dimensional shape involves calculating the total length of its boundary. The perimeter is essentially the distance around the shape.

To find the perimeter, you need to know the lengths of all the sides of the shape. The formula for calculating the perimeter can vary depending on the specific shape you are dealing with. Here are a few examples:

1. Square:
In a square, all sides are equal in length. To find the perimeter, simply multiply the length of one side by 4. For example, if the length of one side is 5 units, then the perimeter would be 5 + 5 + 5 + 5 = 20 units.

2. Rectangle:
In a rectangle, opposite sides are equal in length. To find the perimeter, add the lengths of all four sides. For example, if the length of one side is 5 units and the length of the adjacent side is 10 units, then the perimeter would be 5 + 10 + 5 + 10 = 30 units.

3. Triangle:
In a triangle, all three sides can have different lengths. To find the perimeter, add the lengths of all three sides. For example, if the lengths of the three sides are 3 units, 4 units, and 5 units, then the perimeter would be 3 + 4 + 5 = 12 units.

4. Circle:
In a circle, the perimeter is also known as the circumference. It is calculated using the formula C = 2πr, where "r" represents the radius of the circle. For example, if the radius of the circle is 4 units, then the perimeter (circumference) would be 2π × 4 = 8π units.

Remember that the perimeter is always expressed in the same unit of measurement as the lengths of the sides.
