Rectangles ABCD and EFGH are similar figures because angles A, B, C, and D are congruent to angles E, F, G, and H, respectively.

Question

If DA equals 19 units, AB equals 8 units, and HE equals 133 units, what does EF equal?

A. 56 units
B. 122 units
C. 7 units
D. 315.88 units

Answer 1

DA/HE = AB/EF, so

19/133 = 8/EF
EF = 56

Answer 2

122
