It would be 348
as A= lw+l((w
/2)^2+h^2)^0.5+w((l
/2)^2+h^2)^0.5
where l=12, w=12, h=6
A=347.65 ~ 348

Step-by-step explanation:
8x +9 = 6x + 21 where x = number of chairs in each row
2x=12
x=6
sub back into original equation 8 x 6 + 9 =57 chairs
I dont know if this is right but the answer to 2(12+8x)-3(4x-9) might be 4x+51?
