Answer 1

Pick the right side version from my online generator then update the radius

.ticket {
  display: inline-block;
  width: 500px;
  height: 200px;
  overflow: hidden;
  background: orange;
  /* 20px is the radius, it needs to be smaller than 50px/2 */
  --mask: radial-gradient(20px at right,#0000 97%,#000) 50%/100% 50px;
  -webkit-mask: var(--mask);
          mask: var(--mask);
}

<div class="ticket"></div>
