A rectangular plot 100 m long and 80 m wide has a path 5 m wide all around inside it. Find the area of the path.
A1700 m²
B1800 m²
C1900 m²
D2000 m²
Explanation
Outer area = 100 * 80 = 8000 m². Inner length = 100 – 10 = 90 m, Inner width = 80 – 10 = 70 m. Inner area = 90 * 70 = 6300 m². Area of path = 8000 – 6300 = 1700 m².
