The length and perimeter of a rectangle are the ratio of 5 : 18 What well be the ratio of its length and breadth?

• A. 4 : 3
• B. 5 : 4
• C. 3 : 5
• D. 4 : 7

Answer: (B)

According to the question,l/[2(l + b)] = 5/18? 10l + 10b = 18l = 10b? l/b = 10/8 = 5/4? l : b = 5 : 4Hence, ratio of length and breadth of a rectangle is 5 : 4
