A rectangular garden is 23 m long and 17 m wide. A path 2.5 m wide runs all around the outside of the garden. Find the area of the path.
Answer: The area of the path is .
Step-by-step solution
Step 1: Calculate the area of the inner rectangular garden
The inner rectangular garden has a length of and a width of . Using the standard area formula for a rectangle, , we calculate .
Step 2: Determine the outer dimensions including the path
Since the path has a uniform width of running all around the outside, we add twice the width of the path to both the length and the breadth. The outer length becomes and the outer breadth becomes .
Step 3: Calculate the area of the outer rectangle
Now, we find the total area enclosed by the outer boundary including the garden and the path. Multiplying the outer dimensions gives .
Step 4: Calculate the area of the path
The area of the path alone is obtained by subtracting the inner garden area from the total outer area. Subtracting from yields .
