Hi, Myrn. Seems like you're having problems with these kinds of questions. 

Practice with this. 

Let:
width = x
length = 3x+5

Perimeter= (2*width)+(2*height)

Knowing these, you could come up with an answer for the dimensions. 

Message me if you're having trouble coming up with an answer.

Let x is width
and 3x+5 is lenght
perimeter =810 meters
 
then the formula is 
P=2(3x+5 )+ 2x
810=2(3x+5)+2x
810=6x+10+2x
810=8x+10
810-10 =8x
800=8x
800/8=8x/8
100=x


length=3x+5
length=3(100)+5
length=300+5
length=305
width=100
