Question

The length of a rectangular field is 4 times its breadth if the perimeter of this field is 800 metre then what is the length of the field​

Answer 1

Step-by-step explanation:

let

breadth =x

length=4[breadth] = 4x

perimeter of a rectangle=2(l+b)

800=2(4x+x)

400=5x

x=80

lenght of the field is 4x= 4*80=320m
