Practice Basic JavaScript Functions

Is this an acceptable way of rewriting the below function solution as an arrow function?

Practice Solution: 

 function areaRectangle(width,height) {
  return(width*height)
}

My Arrow function: const areaRectangle= (length,width,height) => return(width*height)

You're close, but the original function only takes two arguments, width and height. Remove the "length" argument from your arrow function to make it like the original.

Also, in the compact form an arrow function does not use the "return" keyword (or the parentheses).
