Answer:

W=7.5 m

L=15 m

Step-by-step explanation:

Let the length be L and width be w

Perimeter of rectangle=45 m

Perimeter of rectangle=2L+2w

So

2L+2w=45 --------------(1)

Now

L=2w----------------------(2)

Putting (2) in (1)

2(2w)+2w=45

4w+2w=45

6w=45

Divide both sides by 6

We get

w=7.5 m

Now

Putting w in (2)

L=2(7.5)

L=15 m
