Question

The ratio between the length and perimeter of a rectangular plot is 1 is to 3 then the ratio between the length and breadth is

Answer 1

Answer:

length:breadth = 2:1

Step-by-step explanation:

given,

length:perimeter = 1:3

=> perimeter:length = 3:1

=> perimeter/length = 3/1

=> 2×(length+breadth)/length = 3/1

=> (length+breadth)/length = 3/2

=> length/length + breadth/length = 3/2

=> 1 + breadth/length = 3/2

=> breadth/length = 3/2 - 1 = 1/2

=> length/breadth = 2/1

=> length:breadth = 2:1
