ella [17]

 The searched polygon can be seen in the attached image.
 The area of the polygon will be the area of the square plus the area of the triangle.
 At = (6) * (8) + (1/2) * (5) * (8) = 68
 At = 68
 answer
 the area of the polygon is 68units ^ 2

Write a rule to describe each transformation
Veronika [31]

Answer:

k = 2

Step-by-step explanation:

the dilation k is the scale factor. A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. To find the scale factor k, we will compare the original points with their transformation

Point R is at (-1,2), and R' is at (-2,4).

divide the ys: 4/2 =2

divide the xs: -2/-1 =2

therefore the scale factor is 2
