A rectangular garden is 20 m long and 12 m wide. A path 2 m wide is built inside the garden, running all around the edge. What is the area of the path?
- A.96
- B.104
- C.112 ✓
- D.120
Explanation: Outer area = 20×12 = 240 m². The remaining inner rectangle is 16×8 = 128 m² (each side shrinks by 2×2=4 m). Path area = 240 − 128 = 112 m².
