Question 888533
Perimeter & rectangle dimensions questions like this are too typical.


L for length
w for width


L=2w+6 and 2w+2L=96.  These are two equations in two unknowns, and easily solved.  


The perimeter equation in this example simplifies to w+L=48.  
Substitute:  w+(2w+6)=48
3w=48-6
3w=42
w=(6*7)/3
w=14--------------one of the answers.


L=2*14+6 = ?
