Question

Two cross roads each of width 10 M cut at right angles through the centre of a rectangular Park of length 600 m and width 200 m and parallel to its side find the area of the roads also find the area of Park excluding Cross Road​

Answer 1

area of roads=7900m²
area of park=120000m²
area of park excluding roads=120000-7900=112100m²

Answer 2

area of road=600×10+200×10
-10×10
=6000+2000-100
=8000-100=7900m^2
area of park=600×200=120000m^2
area of park excluding Cross roads=120000-7900=112100m^2
