A rectangular garden has a length of 20 meters and a width of 15 meters. If a path of 2 meters wide is built around it (outside the garden), what is the area of the path?
Show answer & explanation
Correct answer: B
Explanation
Length of the garden = 20 m
Width of the garden = 15 m
A 2 m wide path is made around it.
Outer dimensions
New length =
20 + 2 + 2 = 24 m
New width =
15 + 2 + 2 = 19 m
Area of the outer rectangle
24 × 19 = 456
Area of the garden
20 × 15 = 300
Area of the path
456 − 300 = 156
Final answer: 156 square meters
