Two Chords \

Don't put your problem in the title of your post, that's why there is
a text box.

We must assume that the two chords are parallel for this question
to make any sense.

From the centre draw a radius to the end of each of the chords,
creating two right-angled triangle

let the distance from the centre to the longer chord be d1
d1^2 + 5^2 = 6^2
d1 = 36-25 = 11
s1 = √11

repeat those steps for the other triangle, add up the two results.
