We know P=2%28L%2BW%29, working eqn
But, L=5%2B2W, subst in our working eqn
P=2%285%2B2W%29%2B2W
82ft=10%2B4W%2B2W
82-10=6W
cross%2872%2912%2Fcross%286%29=cross%286%29W%2Fcross%286%29
highlight%28W=12ft%29
Also, L=5%2B2%2812%29=5%2B24=highlight%2829ft=L%29
In doubt? Go back working eqn,
82=2%2829%2B12%29
82=2%2841%29
82ft=82ft
Thank you,
