Question

the length of a rectangular field is twice it's breadth of perimeter of this field is 800 m what is length of the field​

Answer 1

Step-by-step explanation:

Let the breadth (b) of the rectangular field be x

∴length(l)=2x

As we know that, perimeter of rectangle (P) is given as-

P=2(l+b)

⇒P=2(2x+x)

⇒P=2(3x)

⇒P=6x

Given that perimeter (P) of the rectangular field is 800m

∴6x=800

⇒x= 133.3

Therefore,

Breadth of the field =133.3

Length of the field =2×133.3=266.6m
