In quadrilateral rstu, rs = 60 mm, st = 60 mm, tu = 112 mm, and ur = 112 mm.

if quadrilateral vwxy is similar to quadrilateral rstu, which side lengths could be the side lengths of quadrilateral vwxy?
a.
vw = 15 mm, wx = 15 mm,
xy = 28 mm, yv = 28 mm

b.
vw = 30 mm, wx = 30 mm,
xy = 112 mm, yv = 112 mm

c.
vw = 56 mm, wx = 56 mm,
xy = 108 mm, yv = 108 mm

d.
vw = 60 mm, wx = 60 mm,
xy = 56 mm, yv = 56 mm

A. factor 4

Step-by-step explanation:

Just choose any side of the original one e.g 60mm and divide it by the lenght of the same side of the new one. In A. this gives you 60mm/15mm = 4. Then you can multiply the other lengths with that factor and if the result is equal to the sides of your original one you found the solution.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
