Answer: 2 meters.
Step-by-step explanation:
Let w = width of the cement path.
Dimensions of pool : Length = 15 meters , width = 9 meters
Area of pool = length x width = 15 x 9 = 135 square meters
Along width cement path, the length of region =
width =
Area of road with pool =
Area of road = (Area of road with pool ) -(area of pool)
width cannot be negative, so w=2 meters
Hence, the width of the road = 2 meters.
