your getting lost at writing the equation as the length is 6ft more than three times the width is the key to solving this problem.
The perimeter of a rectangle is 2(W)+ 2(L), we are giving perimeter so we can write our first equation...2(W)+2(L0=124
next write out the second equation which is the sentence your stuck at....... L=3(W)+6
so putting the 2 equations together to get 1 variable we get:
2(W) + 2(3W+6)=124
solve for W=14
solve for L=3 times width add 6
= 3*14+6
L = 48
hope that helps!

you know ___ 2L + 2W = 124

you are given ___ "length is 6ft more than three times the width" ___ L = 3W + 6

substituting ___ 2(3W + 6) + 2W = 124 ___ 8W + 12 = 124 ___ W = 14

plug the value for W into your original equation to find L
