Answer:
- 231 m²

Step-by-step explanation:
<em>See the attached.</em>
The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.
<u>The path is 1 m wide and the total length is:</u>
- 50*3 + 30*3 = 240 m
We need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.
<u>Subtracting the duplicated area 9 x 1 m² to get the total area of the path:</u>
- 240 - 9 = 231 m²
<u>The cost of cementing is:</u>
- 231*20 = 4620
