A vacant lot is being converted into a
community garden. The garden and a
walkway around its perimeter have
an area of 690 square feet. Find the
width of the walkway (x) if the garden
measures 14 feet wide by 18 feet
long. Write answer to 2 decimal
places. (Write the number without
units).
Hint: add 2x to each of the garden
dimensions of 14 x 18 feet to get the
total area for the length multiplied by
width.
