Asked by Jamie
A uniform-width boardwalk is built around the inside edge of a rectangular parkland that is 30 m by 5 m. If the boardwalk takes up 20% of the lot, how wide is the boardwalk to the nearest centimetre?
I know that the total area= 150m^2
boardwalk area= 30m^2 and the parkway area is 120m^2.
I don't know what to do with these numbers.
