Let the breadth of the field be x m Let the length of the field be 3x m Perimeter of the field = 800 m 2(l+b)= 800 2(3x+x)= 800 2(4x)= 800 8x= 800 X= 800/8 X= 100 Therfore,the length = 3x = 3*100m = 300m Breadth = x = 100m Area of the field = l*b=300*100 = 30000 m^2 Hope this helped u Please mark as brainliest answer and click Thanks....

Let the length be 3x and breadth be x
 perimeter = 800 m
 so, 2(l+b) = 2(3x+x) =8x
now, 8x = 800 m
x = breadth = 100 m and 3x = length = 300
so, area = 300 *100 = 30000 m²
