To find the perimeter of an adjoining figure, we need to add up the lengths of all its sides. The perimeter is the boundary around the figure, which can be thought of as the length of a fence enclosing the shape. In this case, we will break down the figure into its individual sides and calculate their lengths before adding them together to find the total perimeter.

Step 1: Identify the figure
First, we need to identify the figure for which we want to find the perimeter. Let's assume we have a figure with four sides.

Step 2: Measure the sides
Next, we need to measure the length of each side of the figure. Use a ruler or any other measuring tool to measure the length accurately.

Step 3: Add up the lengths of all sides
Once we have measured all the sides, we can add up their lengths to find the perimeter. Sum up all the measured lengths to obtain the total perimeter of the figure.

Example:
Suppose we have a figure with sides measuring 5 cm, 7 cm, 6 cm, and 8 cm. To find the perimeter, we add up these lengths: 5 cm + 7 cm + 6 cm + 8 cm = 26 cm. Therefore, the perimeter of this figure is 26 cm.

Step 4: Express the answer
Finally, express the answer in appropriate units. In this example, the perimeter is expressed in centimeters (cm).

Conclusion:
In conclusion, finding the perimeter of an adjoining figure involves measuring the lengths of all its sides and adding them together. The perimeter represents the total length of the boundary around the figure. By following the steps outlined above, we can accurately determine the perimeter of any given figure.
