A rectangular lawn measures 40 m by 30 m. A 2 m wide path is constructed all around the inside of the lawn. What percentage of the lawn's area is occupied by the path?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 22%.
Lawn area = 40 × 30 = 1200 m2
Path width = 2 m
Inner rectangle length = 40 – 4 = 36 m
Width = 30 – 4 = 26 m
Inner area = 36 × 26 = 936 m2
Path area = 1200 – 936 = 264 m2
Percentage = (264/1200) × 100 = 22%
