Length and breadth of a rectangular park is 300 m & 200 m respectively. If a 10 m wide path is constructed outside the park, then find the area (in sq m) of the path.
Explanation:
length of the park = 300 and breadth of the park = 200
Formula used:
Area of rectangle = (length x breadth)
Solution:
Area of park = 300 ×200=60000 m²
Length of park including path = 300 + 2 ×10=320 m
Breadth of park including path = 200 + 2×10=220 m
Area of park including path = 320 ×220=70400 m²
Required difference = 70400 – 60000 = 10400 m²
