A. part 1 abcd is similar to quadrilateral efgh. diagonal ac has length 7 and diagonal eg has length 13. what is the scale factor that describes a dilation from bc to fg? give the exact scale factor and state whether the dilation is an expansion or a contraction.
b. part if side ab has length 17/26 what is the length of side ef? give the exact, un-rounded value.

c. part the area of abcd is 147 square inches, what is the area of efgh? give the exact answer.

i would deeply appreciate it if you could explain how to find the answer
(i'm specifically confused about scale factor and diagonals in part 1) and if you could do a step by step walk through. will give brainliest answer!
