When you were finding the area of walkway, you took the area around walkway border. If you draw the pool and walkway, you should have 2 rectangles. A small rectangle to represent the pool, and a larger rectangle surrounding the smaller rectangle. This large rectangle represents the walkway border. Not the walkway itself. The area between the walkway border and pool is actually the walkway.

So the area of walkway = area of walkway border - area of pool

If the length of the walkway border is 24 m and the width of the walkway border is 16 m, then area of walkway border is

24 m * 16 m = 384 m

^{2}Area of walkway = 384 m

^{2}- 308 m^{2}= 76 m^{2}
