Tests:

clientWidth / clientHeight (destructured and renamed)
const { clientWidth: width, clientHeight: height } = el; const perim = (width + height) * 2;
clientWidth / clientHeight (destructured)
const { clientWidth, clientHeight } = el; const perim = (clientWidth + clientHeight) * 2;
clientWidth / clientHeight (simple property access)
const width = el.clientWidth; const height = el.clientHeight; const perim = (width + height) * 2;
getBoundingClientRect() (destructured)
const { width, height } = el.getBoundingClientRect(); const perim = (width + height) * 2;
getBoundingClientRect() (simple property access)
const rect = el.getBoundingClientRect(); const width = rect.width; const height = rect.height; const perim = (width + height) * 2;
