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
Putting w in (2)
L=2(7.5)
