To do that you'll need the mean and standard deviation of all the scores. Can you provide this info?
For example: Supposing that the mean of these scores were 52 and the standard deviation 3. You'd need to find the "z-score" of 57 in this case.
57 - 52
It is z = ------------ , or z = 5/3, or z = 1.67.
3
Find the area to the left of z = 1.67. Multiply that area by 100% to find the percentile rank of the score 57.

Step-by-step explanation:
Hey There!
So the first step is to find the formula for area of a trapezoid
h = height
b1 = base 1
b2 = base 2
now all we do its plug in the values
Hope this helps!!
