Answer
Width = 1.28 cm
Length = 1.70 cm
Work Step by Step
Set up an equation for appropriate conditions. Factor out expression and add. Subtract .84.
$2(x+.42)+2x=5.96$
Divide both sides by 4 and solve for x.
$4x=5.12$
Solving for x gives you the value for width. Simply add .42 to find the value for length. Don't forget to check these values by substituting them into the original equation!
$x=1.28cm(width)$, $x=1.70cm(length)$
