The length and breadth of a rectangular plot are in the ratio 3:2. If the breadth is 40 meters shorter than the length, what is the perimeter of the plot?

Explanation

Given the length to breadth ratio is 3:2 and the breadth is 40 meters less than the length, let the length be 3x and breadth be 2x. Since length - breadth = 40, we have 3x - 2x = 40, so x = 40. Therefore, length = 120 meters and breadth = 80 meters. The perimeter = 2 × (length + breadth) = 2 × (120 + 80) = 400 meters.
