Question

the area of a rectangular field is 4500 sq.m If its length and breadth are in the ratio 9is to 5then perimeter is

Answer 1

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..
