Question

a rectangular frame length and breath ratio is 5 :3 if frame length is 20 centimetres then what is width

Answer 1

Answer:Width is 12cm

Step-by-step explanation:

Ratio of length to width=5:3

Let length and width be 5x and 3x

Length= 20cm

5x= 20

x= 20/5= 4

Width of the rectangle= 3x= 3X4= 12cm

Answer 2

the ratio of length and breadth is 5:3..
and length of the farm is 20 cm..

now..
we have to find the breadth..
let the breadth be 'x'

$\frac{5}{3} = \frac{20}{x}$

:.
$\frac{3 \times 20}{5} = x$
:.
$x = 12$
