The width is 8.2
Perimeter = 2W + 2L (there are four sides of a rectangle, two longer sides, two shorter, W and L)
<span>65.6 = 2W + 2L
</span><span>L = 3W so substitute 3W in for L </span>
<span>65.6 = 2W +2 (3W) </span>
<span>65.6 = 8W </span>
<span>W = 8.2 cm </span>
<span>L = 3(8.2) </span>
<span>L = 24.6cm </span>
