I have a problem with add width and height value for image on AMP. Can anyone please tell me how to do it?

Old code:

<img src="/url-img1.jpg" with="728"></img>
<img src="/url-img2.jpg" with="640"></img>

And in AMP version:

<amp-img src="/url-img1.jpg" width="{widht-of-image}" height="{height-of-image}" layout="responsive"></amp-img>
<amp-img src="/url-img2.jpg" width="{widht-of-image}" height="{height-of-image}" layout="responsive"></amp-img>
