Arectangle has a width of 5 inches and a length of 9 inches. what will be the new dimensions of the rectangle after it is dilated by a scale factor of 3?

8 inches by 12 inches
15 inches by 9 inches
15 inches by 27 inches
45 inches by 81 inches

The correct answer is:

C. 15 inches by 27 inches.

The new dimensions of the rectangle after it is dilated by a scale factor of 3 will be 15 inches by 27 inches.

b

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.
