&lt;br&gt;
Perimeter = 2 length + 2 width
L = W + 3.4
P = 45.8
Put the known values into the formula
P = 2L + 2W
45.8 = 2(W+3.4) + 2W
Distribute
45.8 = 2W + 6.8 + 2W
Add
45.8 = 4W + 6.8
Subtract 6.8 from each side
39 = 4W
Divide each side by 4
w = 9.75
If the width is 9.75 and the length is 3.4 more than that, the length = 13.15
9.75 + 9.75 + 13.15 + 13.15 = 45.8</PRE>
