Answer 1

With an svg, it is pretty simple :

svg {
  display: block;
  width: 100%;
  height: 90px;
  background: yellow;
}

Note that I used the preserveAspectRatio="none" attribute so that the shape can have 100% width and keep 90px height

And here with a monkey image :

div {
  position: relative;
}
svg {
  display: block;
  width: 100%;
  height: 90px;
  background: yellow;
}
img {
  height: 50px;
  position: absolute;
  top: 0; bottom: 0;
  left: 0; right: 0;
  margin: auto;
  background: #fff;
  border-radius: 50%;
  padding: 10px;
}
