Answer:
Length: 7
Width: 4
Step-by-step explanation:
We can create a system of equations for this problem, where 
 is the width and 
 is the length.
The perimeter of a rectangle is twice its length added to twice its width.

The length is 3 more than the width:

We can now substitute in 
 as 
 in the equation 
.

Distribute the first terms:

Combine like terms:

Subtract 6 from both sides:

Divide both sides by 4:

Now we know that w = 4. We can now substitute this inside an equation to find 
.

Hope this helped!
