Answer:
6x + 26 feet
Step-by-step explanation:
Assuming the garden is a rectangular shape, we have four sides, where two sides are 2x + 6 feet and two sides are x + 7 feet. To find the perimeter, we add up the lengths of all four sides.
2x + 6 + 2x + 6 + x + 7 + x + 7
or
2(2x + 6) + 2(x + 7)
6x + 26
