Question

if the ratio between the breadth and the perimeter of a rectangle is 1:8 , find the ratio between its length and breadth​

Answer 1

Answer:

The length would always be 8

Step-by-step explanation:

e.g if breadth  is 40 and perimeter is 320 the length would be 8 that is impossible because the length is always more than breadth lets try 5

breadth= 5 and perimeter =40 the length will still be 8 although is possible it can be 5:8

Answer 2

Answer:

3 : 1

Step-by-step explanation:

Suppose that Length = L and breadth = B

So perimeter = 2(L+B)

According to question

B : 2(L+B) = 1 : 8

or, B/(2L+2B) = 1/8

or, 8B = 2L+2B

or, 8B-2B = 2L

or, 6B = 2L

or, L/B = 6/2

or, L/B = 3/1

So, L : B = 3 : 1
