(x+10(2x+5)) to find the area of the full shape
2x^2+5x+20x+50
2x^2+25x+50 (simplified), then subtract the area of the square inside which is
(x+1)(x+1) = x^2+x+x+1 = x^2+2x+1
(2x^2+25x+50)-(x^2+2x+1)
x^2+23x+49 is the final answer

X = the value of observation

\bar{X} is mean of the observations and

σ = standard deviation of the score

Applying values we get

Z=\frac{59-72}{4.2}=-3.09
