You are building a rectangular garden against the back of your house, using 80 feet of fencing. The area of the garden needs to
be greater than 400 square feet but less than 600 square feet. Which interval(s) represent possible lengths, in feet, for the horizontal edges of the garden? (0, 10) Union (30, 40) (20 minus 10 StartRoot 2 EndRoot, 20 + 10 StartRoot 2 EndRoot) (0, 20 minus 10 StartRoot 2 EndRoot) union (20 + 10 StartRoot 2 EndRoot, 40) (20 minus 10 StartRoot 2 EndRoot, 10) Union (30, 20 + 10 StartRoot 2 EndRoot)
The answer for your question is C. The reason is I multipled 15 and 6 which gave me 90 and that is closest to the answer C which is 72.73.
Hope this helps:)
