ok so you have 300 in total, here is your equation you're going to use:
L= 3w-10
So you have: w+w+3w-10+3w-10=300
So now you have: 8w-20= 300
Add 20 to both sides: 8w-20+20=300+20
Now you have: 8w=320 
Divide both sides by 8: 8w/8=320/8
w=40
Now fill in w to the length equation
L= 3(40)-10 
L= 110 
So your width is 40 and your length is 110
