A 3 m wide path runs outside and around a rectangular park of length 125 m and breadth 65 m. Find the area of the path.

Length of rectangular park = 125 m,
Breadth of rectangular park = 65 m and
Width of the path = 3 m
Length of rectangular park with path = 125 + 3 + 3 = 131 m
Breadth of rectangular park with path = 65 + 3 + 3 = 71 m
∴ Area of path = Area of park with path – Area of park without path
= (AB x AD) – (EF x EH)
= (131 x 71) – (125 x 65)
= 9301 – 8125
= 1,176 m²
Thus, area of path around the park is 1,176 m².
