the cross roads,each width 5m, run at right angles through the centre of a rectengular park of length 70m and breadth 45m and parallel to its sides. find the area of roads

Answer 1

area of first road=5×70=350m^2
area of second road=5×45=225m^2
total area=350+225=575m^2
cross section area of roads=5×5=25m^2
area of roads=575-25=550m^2
