Question 1060790
Let x be the width of each strip; three of such strips will be added.


The new size will become  (8+x) in the long direction and (6+2x) in the short direction.


<i>...the area of the deck is tripled. how wide should that strip be ?</i>
{{{(x+8)(2x+6)=3(6*8)}}};
Can you simplify and solve this?
