Question 150812
width=w
length=2w+3


2(w)+2(2w+3)=90


Divide both sides by 2
(w)+(2w+3)=45


Combine like terms
3w+3=45


Subtract 3 from both sides
3w=42


Divide both sides by 3
w=14


width=w
length=2w+3


width=14
length=2(14)+3
length=28+3
length=31


Answer:
*width=14 meters*
length=31 meters
