The ratio of the length and breadth of a plot is 4 : 3. If the breadth is 40 m less than the length, What is the perimeter of the plot?

Let the length be 4x metres. Then, breadth = 3x metres.
Then, 4x - 3x = 40 => x = 40 
length l = (4 × 40) = 160 m 
breadth b = (3 × 40) = 120 m 
Perimeter = 2(160 + 120) = 2(280) = 560 m
