A) \[(l+w)\,(b+w)-lb\]
B) \[l\,b-(l-w)\,(b-w)\]
C) \[(l+b-w)w\]
D) \[l\,b-(l-2w)\,(b-2w)\]
Correct Answer: C
Solution :
Area of the path along length \[=l\times w\] Area of the path along breadth \[=l\times w\] The common area of the paths \[={{w}^{2}}\] \[\therefore \]Total area of the path\[=lw+lw-{{w}^{2}}=(l+b-w)\,w\]You need to login to perform this action.
