Question

if the ratio between the length and perimeter of a rectangular field is 1:3 then its length and breadth are in the ratio of​

Answer 1

Answer:

Let the length be x.

Therefore, perimeter = 3x

since

3x = 2(x +b)

3x = 2x + 2b

x = 2b

ratio = length : breadth

=x : b

=2b : b

=2:1

Answer 2

Ans = 2:1

length:2(l+b)=1:3

Let L be x

$then \: \: 2(l + b)is \: equal \: to \: 3x$

Therefore b=( 3x/2 -x)= x/2.

So,L :b = x: x/2= 2:1

hence the answer is 2:1
