The length and perimeter of a rectangle are in the ratio of 5:18. What will be the ratio of its length and breadth?
Correct Answer: Description for Correct answer:
According to the question,
\( \Large \frac{l}{2(l+b)}=\frac{5}{18} \)
=> 10 l+ 10 b=18 l => 8 l=10 b
=> \( \Large \frac{l}{b}=\frac{10}{8}=\frac{5}{4} \)
l : b = 5 : 4
Hence, ratio of length and breadth of a rectangle is 5 : 4.
