Explanation:
To find the total perimeter of Tara's garden including the walkway, we need to add the perimeter of the garden to the perimeter of the walkway.
Let's assume that the garden is a rectangular shape. We can find the perimeter of the garden by adding up the lengths of all four sides.
For example, if the length of the garden is 10 feet and the width is 8 feet, then the perimeter of the garden would be:
P_garden = 2(10 feet) + 2(8 feet) = 20 feet + 16 feet = 36 feet
Now, if the walkway is 2.5 feet wide, we need to add 2.5 feet to the length and width of the garden to get the dimensions of the entire area.
For example, if the garden is 10 feet by 8 feet, then the entire area (including the walkway) would be 15 feet by 13 feet (10 feet + 2.5 feet + 2.5 feet by 8 feet + 2.5 feet + 2.5 feet).
We can now find the perimeter of the entire area by adding up the lengths of all four sides:
P_total = 2(15 feet) + 2(13 feet) = 30 feet + 26 feet = 56 feet
Therefore, the total perimeter of Tara's garden including the walkway is 56 feet.
