The answer is false
because the area of a triangle is 1/2 b*h
so in this case, it would be 1/2 15 * 8
and 15 * 8 = 120 and 120 divided by 2 = 60 not 40
A + s = 504
s = a + 54
a + (a + 54) = 504
2a + 54 = 504
2a = 504 - 54
2a = 450
a = 450/2
a = 225 <=== adults
a + s = 504
225 + s = 504
s = 504 - 225
s = 279 <=== students
