2L + 2W = P
2L + 2W = 340
L = 3W-6
Substitute the known value of L from the bottom equation into the previous one.
2(3W-6) + 2W = 340
6W-12+2W = 340
8W-12 = 340
Add 12 to each side
8W = 352
Divide each side by 8
W = 44
.
If the width is 44, the length is (3*44)-6, or 126
Perimeter fencing = 126+126+44+44, or 340
