The formula for dilating a rectangle by a scale factor is:
Area after dilation = (scale factor)^2 * original area
In this case, the scale factor is 3/4, so the area after dilation would be:
Area after dilation = (3/4)^2 * 9191
Area after dilation = (9/16) * 9191
Area after dilation = 5160.1875
Rounding to the nearest tenth, the area after dilation is approximately 5160.2 units squared.
A rectangle with an area of 9191 unitssquared
