The perimeter of a rectangular field is 480 meters and the ratio between the length and breadth is 5:3. The area of the field is:

Ratio of Length and Breadth = 5:3 Let the length and the breadth of the rectangle = 5x and 3x respectively According to the question Perimeter = 2(l+b) = 480 2(5x + 3x) = 480 x=30 Therefore, Length = 150m and Breadth = 90m Area of Rectangle = 150 × 90 = 13500 m^{2}
