What is my next step?

[sudden hull]

The base will look like this, but I don't know how to get the area of the chord without trignometry

I know that we can also use [sector]-[triangle] but I don't know the central angle and I don't see a special triangle right now

Reflect one of those right angled triangles by the chord and notice that you get an equilateral triangle. This allows you to get the central angle

You can also compute the area of that triangle by first using Pythagorean theorem to get the length of the chord

i see thanks

[sudden hull]

is the answer 1105?

[olive pike]

Yes, that should be correct
