Question : There is a rectangular garden of 150 m × 25 m. A path of width 10 m is built around the garden. What is the area of the path?
Option 1: 3700 m2
Option 2: 3550 m2
Option 3: 3900 m2
Option 4: 3220 m2
Correct Answer: 3900 m 2
Solution :
Given: There is a rectangular garden of 150 m × 25 m. A path of width 10 m is built around the garden.
Here, the length of the garden ($l$) = 150 m
The breadth of the garden ($b$) = 25 m
The width of the path ($w$) = 10 m
So, the area of the path = $2w(l+b+2w)$
= $2×10×(150+25+20)$
= $20×195$
= 3900 m

Hence, the correct answer is 3900 m
