The formula for the area of a trapezoid is A=1/2(base one+base two)h
All you have to do is find the base one, base two, and height using the given information and then plug it into the equation.
Multiply the z-score by the standard deviation:
2 x -1.5 = -3
Now add that to the mean:
49 + -3 = 46 inches.
The first number after that matching the criteria is 106644, as 33 is below so the closest one has to be at 44.
I believe the answer is A "If a triangle is equilateral, then it has three congruent angles". Hope this helps!
