Answer:
The total area of the pond and walkway = 324 [tex]ft^{2}[/tex]
Step-by-step explanation:
Given:
Length of square pond = 15 feet
Walkway = 3 feet
Determine the area of pond + the walkway
Total length = pond length + Walkway
Total length = 15 feet + 3 feet
Total length = 18 feet
Now, the required area can be calculated as thus:
Area = total length × total length
Area = 18 × 18
Area = 324 [tex]ft^{2}[/tex]
