1. Your mission is to dilate the rectangle shown below by a scale factor of 8. (a) Calculate the length of each side of the dilated image you’ve created, and make certain to include your work below. You’ll need this for Part B.
Draw the new image, label it , and put the measurements you calculated in Part A on your new figure with the appropriate units. The image does not have to be to scale but should visually show whether it is a reduction or an enlargement.
its a rectangle with 15 cm on top and on the side 4cm

(x, y)→(x − 8, y − 7)

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
