The area of a trapezoid = 0.5h(a + b) where a and b are the lengths of the parallel sides
so here we have 0.5(8)(a + 12) = 144
solve for a
4(a + 12) = 144
4a + 48 = 144
4a = 96
a = 96/4 = 24
Z score = n - mu / d where mu = mean and d = std dev.
for n = 14 we hav ez score of (14-20) / 2.8 = -2.143
unusual as he is in the bottom 5%
