Example 8: A path 2.5 m wide is running around
a square field whose side is 45 m. Determine the​

Answer 1

Step-by-step explanation:

The path is 2.5 m wide.

The length of the square field is 45 m.

We know, area of square = (length)2 unit

Hence, area of the square field $$= (45)^2 m^2 \\ = 2025 \, m^2$$

Now considering the path we have now the side of the filed =(45+(2.5×2))m=(45+5)m=50m

[since the path is a round]

Hence the area of the square filed including the path =(50)2m2=2500m2

∴ Area of the path =(2500−2025)m2=475m2

∴ option A is correct.
