Barbara, You should draw a diagram. I assumed the walkway was the same width all the way around and called the width x feet. I then cut the walkway into 4 pieces as in the diagram. Two of the pieces are 15 feet by x feet and the other two are 10 + 2x feet by x feet. What is the total area of the four pieces? Set this equal to 186 square feet and solve for x. Harley
