Try visualising or drawing a rough figure first.
Find areas of rectangles with respect to length and width
Exclude the area of the figure you will form at the centre.
Area of road = Area of the rectangle with length as 90m and width s 3 m + area of the rectangle with 60 as length and 3m as width - the area that is common to both having sides 3m each.
