A rectangular garden has length twice as great as its width. A second rectangular garden has the same width as the first garden and length that is 4 meters greater than the length of the first garden. The second garden has area of 70 square meters.
Let w be the width of the second garden. Then, its' length is 2w+4. So: w(2w+4)=70 2w²+4w-70=0 w²+2w-35=0 (w+7)(w-5)=0 w=5 2w=10 2w+4=14 The first garden is 5m x 10m, the second is 5m x 14m ☺☺☺☺
