We can find the standard deviation of D by adding the variances of the heights and taking the square root:

Representing probability with area
When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:
A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.

μ=10
σ=9
To find the area of both you would need to multiply the b-base times the height and then divide ur answer by 2 so in #1 you would multiply 4 times 10 and then that would be 40 and divide that by two making your answer 20. and for the trapazoid the formula is a+b divided by 2 and then multiply that all by ur height and your answer would be 91.
