# boundingBox method

Rectangle<num> boundingBox (Rectangle<num> other)

Returns a new rectangle which completely contains `this` and `other`.

## Implementation

    Rectangle<num> boundingBox(Rectangle<num> other) {
      var right = max(this.left + this.width, other.left + other.width);
      var bottom = max(this.top + this.height, other.top + other.height);

      var left = min(this.left, other.left);
      var top = min(this.top, other.top);

      return new Rectangle<num>(left, top, right - left, bottom - top);
    }
