Which of the following statement describes the term perimeter correctl...
Perimeter:
The term perimeter refers to the total distance around the boundary of a two-dimensional figure. It is commonly used to measure the length of the outline or the boundary of a shape. The perimeter is an important concept in geometry as it helps us understand and calculate the length of the sides of various shapes.
Statement:
The correct statement that describes the term perimeter is option 'B' - "The sum of all the lengths of a figure is called its perimeter."
Explanation:
To understand why option 'B' is the correct statement, let's break it down further:
Sum of all the lengths:
The perimeter of a figure is determined by adding up the lengths of all its sides. Each side contributes to the total distance around the figure. For example, in a rectangle, the perimeter is found by adding the lengths of all four sides.
Definition:
The perimeter is the measure of the distance around a figure or object. It is calculated by adding up the lengths of all the sides. The unit of measurement for perimeter is typically the same as the unit used to measure the sides (e.g., centimeters, inches, etc.).
Example:
Let's consider an example of a rectangle with sides measuring 5 cm and 8 cm. To find the perimeter, we add up the lengths of all four sides:
Perimeter = 5 cm + 8 cm + 5 cm + 8 cm = 26 cm
In this example, the perimeter of the rectangle is 26 cm.
Conclusion:
The correct statement that describes the term perimeter is option 'B' because it accurately defines the perimeter as the sum of all the lengths of a figure. This definition helps us understand how to calculate the perimeter of different shapes by adding up the lengths of their sides.
