The area of a rectangle is 2880 sq.cm and the ratio of its length and breadth is 5 : 4. What is the ratio of the breadth to the perimeter of the rectangle?
2 : 9
Let the length and breadth of the rectangle be `l' and `b' respectively -
l:b = 5:4
lb = 2880
Solving we get b = 48, l = 60
So, required ratio = 48 : 2(60+48) = 2 : 9
