Your answer should be 2x/3. You just have to “translate” the English words two thirds into the corresponding mathematical terms.
Let the width of the board be w feet, so the length will be (w+3) feet. The perimeter is the distance all the way round, so we have to add the lengths of the sides together:
w + w + (w + 3) + (w + 3) = 4w + 6.
Hope this helps, Twiggy.
