If she answered all then she would have gotten 179 wrong. If I understand 200 questions and 11% on the test then 179 wrong and 21 right. So if you are asking how many she did not answer I would assume the questions she got wrong were the questions she did not answer which would be 179.

Hello, I hope this helped and that I was right, have a nice day.
Hi I couldn’t do the work for the surface area on the picture because I didn’t have space left so here it is,
Formula: 2(lw+lh+wh)
Shape 1
(2.4 x 1.1) + (2.4 x1.8) + (1.1 x 1.8)= 8.94
8.94 x 2= 17.88
Shape 2
(2.4 x 1.1) + (2.4 x 0.5) + (1.1 x 0.5) = 4.39
4.39 x2 = 8.78
17.88+ 8.78
