The length of a rectangular field is thrice its breadth. If the perimeter of the field is 320, find its length and breadth.​

Answer 1

Step-by-step explanation:

let lenght of rectangular flield be x

length of rectangular field thrice its breadth 3x

perimeter of rectangular field 320

2(l+b)=320

2(x+3x)=320

4x=160

x=160/4

x=40

Answer 2
