Please refer the above image!!
Total length of the field = 30m
Area of the square field (ABCD) = S×S
= 30m × 30m
= 900m²
Width of the path = 1m
Width of the path both the sides = 2m
PQ = AB - 2M
= 30m - 2m
= 28m
Area of square PQRS = S×S
= 28m×28m
= 784m²
Area of the path = Area of ABCD - Area of PQRS
= 900m² - 784m²
= 116m²
Therefore, the area of the Path = 116m²
