Width = W
Length = (4 Less than 3 times the width)
$\left(3×W-4\right)\phantom{\rule{0ex}{0ex}}\text{Length}=\left(3W-4\right)\phantom{\rule{0ex}{0ex}}L=\left(3W-4\right)\phantom{\rule{0ex}{0ex}}=\left(2W-4\right)×W\phantom{\rule{0ex}{0ex}}=W\left(3W-4\right)\phantom{\rule{0ex}{0ex}}=3{W}^{2}-4W$
So the Area of Rectangle = $3{W}^{2}-4W$
