Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)

Answer:

Step-by-step explanation:

Since y varies inversely with x, the relation between y and x will be:

$y \propto \frac{1}{x}$

Introducing the proportionality constant, we can write:

$y = \frac{k}{x}$

Using the first set of given values of x and y, we get:

$50=\frac{k}{10}\\\\k = 500$

This means, the relation between y and x is:

$y = \frac{500}{x}$

We have to find y if x = 20. Using this value in above equation, we get:

$y=\frac{500}{20} \\\\ y = 25$

Thus y would be 25 if x is 20.
