X/29 = 2/5.8
(X) x (5.8). (2) x (29)
5.8x = 58
58/5.8
X = 10
12 x 12 = 144
144 / 58 = 2.66

Answer:
1083 seats
Step-by-step explanation:
i just answered that.
arithmetic sequence
a1 = 10
an = an-1 + 1 = a1 + (n-1)×1 = 10 + (n-1) = 9 + n
a38 = 9 + 38 = 47 seats
the sum of such an arithmetic sequence
n×(a1 + an)/2
in our case
38×(10 + 47)/2 = 19×57 = 1083 seats
