Question

the length of a rectangular field is twice it's breadth . if the perimeter of the field is 150 metres ,find its length and breadth.​

Answer 1

Answer:

Review it, if answer is correct

Step-by-step explanation:

Length  = 2x

Breadth = x

Perimeter = (l+b)*2 = (2x+x)*2 = 150

6x = 150

x = 25

Length = 2x = 50

Breadth = x =25

Answer 2

Let breadth of field be=x
Therefore length of field =2(breadth)=2x
Perimeter=150m

Perimeter of a rectangle=2(l+b)
150=2(2x+x)
150=2(3x)
150=6x
x=150/6
x=25
Therefore breadth=x=25
Length=2x=2(25)=50
