Length of pool 25 feet
Width = 10 feet
width of side walk=2.5m
Area = 25 * 10 250 m^2
Length with concrete walkway = 25+5=30m
width with concrete walkway = 10+5=15m
Area of pool+ walkaway= (10+5)(25+5)
Area of pool+ walkaway= 450
Area of walkway = area of (pool+walkway)-areaof garden=
450 - 250
Area of walkway= 200 m^2
