Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.

Answer:

therefore, the width of the rectangle is 10m and length is 20m.

Step-by-step explanation:

Let n represent width

Let n represent width #2

let 2n represent length

let 2n represent length #2

n+n+2n+2n=60

6n=60

n=60/6

n=10

width=10

length= 2n

= 2*10

=20
