jeramy laureano answered question 3/7/2011 Suppose you want to build a small walkway around your garden so that there is someplace to walk around and work on your vegetables. The garden measures 20 feet by 30 feet and you want to increase the area of the garden to 1,000 ft2. What is the width? (20+x) x (30+x)-600=1000 600+20x+30x+x^2-600=1000 the 600's cancel out 20x+30x+x^2=1000 50x+x^2=1000 50x/50+x^2=1000/50 x^2=20 sqrt x^2=sqrt 20 x=4.4721 x=4.5(approx)
