find the area of path running inside if the square field of 10m and width of path is 2 m. find the cost of leveling at rs 2.50 per sq metre.

Each side of square field = 10 m
Then, area of the field = 102 = 100 m2
Width of the path inside the field = 2 m
Then, each side of the field excluding path = 10 - 2 - 2 = 6 m
So, area of the field excluding path = 62 = 36 m2
Therefore, area of the path = area of the field excluding path - area of the field = 100 m2-36 m2 = 64 m2
Cost of levelling per square metre = Rs.2.50
So, total cost of levelling the path = 64×2.50 = Rs.160
