Question

The ratio Between the length and the perimeter of a rectangular plot is 1:3 and the ratio between the breadth and perimeter of that plot is 1:6.What is the ratio between the length and area of that plot?

Answer 1

Answer:

In the rectangle

length l, breadth b, perimeter p

2l + 2b = perimeter p

also ratio of l to p is 1:3

so p = 3l

therefore, 2l + 2b = 3 l

or 2b = l

So the ratio of l : b is 2 : 1

2l + 2b=3l

l =2b
