Question

if the ratio between the length and perimeter of a rectangleular plot is 1:3 then the ratio between the lenght and breadth of the plot is:

a) 1:2
b) 2:1
c) 3:2
d) 2:3​

Answer 1

Answer:

l:b=2:1

Step-by-step explanation:

let proportionality constant be x

length=x and perimeter=3x

perimeter=2(l+b)

3x =2*(x+b)

3x/2=x+b

b=3x/2-x=x/2

ratio of l and b=x:x/2=2:1
