L x (times) w ( length times width) 9x4=36 I think.
There are 2 methods you are taught in Middle School.
Elimination and Substitution.
Number of seats = 42
Seats per row x row = 1302
s x r = 1302
rows + 11 = seats per row
r + 11 = s
s x r = 1302
(r + 11) x r = 1302
r^2 + 11r = 1302
r^2 + 11r - 1302 = 0
(r + 42) x (r - 31) = 0
r = -43 or 31
Cannot have negative rows so the number of rows is 31, and the number of seats per row is 31 + 11 = 42
Check: 31 x 42 = 1302 :)

False. It only relates to the sides of a right triangle in a simple way, so that if the lengths of any two sides are known, the length of the third side can be found.
