Before you even start calculating the solution to that exercise, the first thing
to do is make sure that you understand exactly what you're looking for. As I read
your question carefully, I'm not convinced yet that you know what's required.
"The length of ..." means one single object, item, or drawing, and you've described
at least two things ... the two chords, which, if they intersect, produce four pieces.
What length are you looking for ? The length of one chord ? Of the other chord ?
Of the short piece of one chord on one side of their intersection ? Of the long piece
of the other one ?
After you clearly understand what the question is, there's a step that usually helps
when you're working with chords: Draw lines from the center of the circle to the ends
of the chord. Each of those lines has the same length ... the radius of the circle. That
often gives you some triangles in which you can find the lengths of unknown sides.
If two chords intersect within a circle, the product of the two segments of one chord equals the product of the two segments of the other chord. In short, if two chords intersect in a circle, their length is equal.
just two parallel chords!
Two angles are not enough to define the length of anything in a triangle. You also need to know the length of one side.
assuming the shape is a quadrilateral, multiply the length by two then multiply the width by two and add those two together for your answer
you multiply the length by two then you multiply the width by two and then add the two answers 2l+2w

There are two or more notes in a chord. Guitar chords usually have three notes... look on wikipedia.com and look up guitar chords or musical chords or something Piano chords are usually 3 notes. Minor addition: "Chords" aren't usually three notes. Triads are three notes, but a chord can be any number of notes, 2 or more.
just two parallel chords!
Depends on the chords you are talking about. Major chords have a major third then a minor chord Minor chords have a minor third and then a major chord Augmented chords have two major thirds Diminished chords have two minor thirds
TWO (2)
The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.

Not true. If the associated central angles are equal, the two chords would be equal.
The two chords at the end of a musical phrase are called a cadence.
Plagal cadance is a cadence formed by two chords at the end of a phrase, the subdominant to tonic chords (IV-I)
