You're not showing the complete picture. However, figures are similar is correspondent sides are proportional. So, option B is not similar to EFGH, because the proportion between correspondent sides would be

which is false.

We can't read the length of side AD, but is should be 6, so that the proportion

would be true. In that case, option A is similar to EFGH.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

1/4 because there is 4 grades.
