Question

i) Two cross roads of width 10 m running parallel to the length and the breadth of a rectangular park are cut at right angles. If the length and the breadth of a park are
900 m and 500 m respectively, find the area of the cross roads.

Answer 1

Answer:

13000$m^{2}$

Step-by-step explanation:

Area of the road along length = 900m * 10m

                                                  = 9000$m^{2}$

Area of the road along the breadth = 500m * 10m

                                                           = 5000$m^{2}$

Area of the common road = 10m * 10m

                                           = 100$m^{2}$

Area of the crossroads = (9000$m^{2}$ + 5000$m^{2}$) - 100$m^{2}$

                                       = 14000$m^{2}$ - 100$m^{2}$

                                       = 13000$m^{2}$
