Given Ratio of Length and Breadth= 9:5
Let Length be 9x and Breadth be 5x
we know that...
Area of the Rectangle= L × B
given Area =4500sq.km.
9x×5x = 4500
45x^2 =4500
x^2 = 100
x=10.
so length= 9x = 9×10 =90
breadth = 5x = 5×10 =50
We know that Perimeter of the Rectangle=
2(L + B)
=2(90+50)
=2(140)
=280sqm..
