Question 204102
use L for length and W for width:

Perimeter is: 2*L + 2*W = 28.
Length is 2 meters more than twice the width: L = 2*W+2.

Use the above for length in the perimeter:

2*(2*W+2) + 2*W = 28.

*[invoke explain_simplification "2*(2*W+2) + 2*W = 28." ]

So, width = 4. 

Since length = 2*W+2, length = 2*4+2 = 10.

Answer: Width = 4, length = 10.
