Perimeter
The perimeter of a shape is the total length of the boundary or the distance around the shape
The perimeter of a shape is the total length of the boundary or the distance around the shape. It is calculated by adding up the lengths of all the sides of the shape.
To find the perimeter of a rectangle, you can use the formula:
Perimeter = 2 * (length + width)
For example, let’s say you have a rectangle with a length of 6 units and a width of 4 units.
Substituting the values into the formula:
Perimeter = 2 * (6 + 4)
Perimeter = 2 * 10
Perimeter = 20 units
So, the perimeter of the rectangle is 20 units.
To find the perimeter of a triangle, you need to add up the lengths of all three sides. If the triangle is an equilateral triangle (all sides are equal), you can use this formula:
Perimeter = 3 * side length
For example, let’s say you have an equilateral triangle with a side length of 5 units.
Using the formula:
Perimeter = 3 * 5
Perimeter = 15 units
So, the perimeter of the equilateral triangle is 15 units.
However, if the triangle is not equilateral and has different side lengths, you need to find the lengths of all three sides first and then add them up to find the perimeter.
In general, the perimeter of any polygon can be found by adding up the lengths of all its sides. The specific formulas to use will depend on the shape and its attributes.
