Answer

22 feet

Work Step by Step

The first side of the wall has a storage of 7 feet plus 5 equal lengths for plants. Make x equal to the length of each plant. The equation of the length would be: 7+5x The second side has a storage of 4 feet plus 6 equal lengths for the plants. The equation of the length would be: 4+6x Set both equations equal. 7+5x=4+6x Subtract 5x from each side. 7=4+6x−5x 7=4+x Subtract 4 from both sides to get : 3=x If x=3, we can plug this in to find the storage length. Lets plug it into equation 1: (7+5x) 7+(5×3)=22 feet
