Question

if the lengh of a rectangle and its perimeter are in the ratio 5:16,then find the ratio between its length and breadth​

Answer 1

Answer:

Length = 5

Perimeter = 16

Breadth = ?

according to the formula:-

P = 2(L+B)

=> 16 = 2(5 + B)

=> 10 + 2B = 16

=> 2B = 16 - 10

=> B = 6/2

=> B = 3.

As we know,

Length = 5

and, by the above calculation

Breadth = 3.

•°• The ratio of length and breadth is 5:3.

hope it helps you....

Answer 2

Answer:

5:3

Step-by-step explanation:

we know, 2(length+breadth)= perimeter.

let the breadth be x.

thus, 2(5+x)=16

2x= 16-10= 6

x= 6/2= 3

thus, ratio required= 5:3
