A rectangular garden is 20 m long and 14 m wide. A path 1 m wide is built inside along all four sides. What is the area of the remaining garden?
Hint
Reduce both dimensions by 2 metres.
Answer
216 m².
Explanation
The inner rectangle is 18 m by 12 m because the 1 m path removes 1 m from each side. Its area is 216 m².
Step-by-Step Solution
Inner length = 20-2 = 18m.
Inner width = 14-2 = 12m.
Area = 18×12 = 216m².
Inner width = 14-2 = 12m.
Area = 18×12 = 216m².
