Answer 2

\[2x+2y = 22\]
x= length
y = width
\[x = 2y +2\] becomes a system of equations at this point.

Answer 3

I don't get it

Answer 4

Perimeter = 22, it says the perimeter of a rectangle is twice the sum of its length and its width , so we get 2x+2y = 22, and its length is 2 meters more than twice its width, so we get x = 2y+2

Answer 5

Now you can use any method to do the systems of equations

Answer 6

y=3..?

Answer 7

But I'm trying to find the length

Answer 8

Once you figure out the width, plug it in any of the original equations and find the length.

Answer 9

Its 8?(:
