Question

Two crossroads, each of width 10 m, cut at right angles through the center of a rectangular park of length 450 m and breadth 270 m and parallel to its sides. Find the area of the roads. Also, find the area of the park excluding crossroads.

Answer 1

Answer:

105400 m

Step-by-step explanation:

Area of Long Road = 450m * 10

                               = 4500m

Area of Short Road = 270m * 10

                               = 2700m

Area of common part = 10*10

                                = 100m

Area of Roads        = 4500 + 2700 - 100 m

                               = 7100 m

Area of Park           = 450m * 250m

                               = 112500 m

Area of park excluding roads = 112500 - 7100 m

                                                 = 105400 m
