**Steve**, Monday, December 5, 2011 at 11:55amLet the walkway have width w

The new dimensions of the garden are

(30-2w) x (40-2w)

That's half of the original area, 30x40

(30-2w)(40-2w) = 1/2 * 30*40

1200 - 140w + 4w^2 = 600

4w^2 - 140w + 600 = 0

w^2 - 35w + 150 = 0

(w-5)(w-30) = 0

w=30 doesn't make much sense. No garden left

w=5 means that the new garden is

20x30 = 1/2 of 30x40
