A rectangle with an area of 47 m² is dilated by a factor of 7. What is the area of the dilated rectangle?
MA_775_DIABLO [31]
We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:

 Ad= (47)(7^2)
 Ad= 47x49
 Ad= 2303 m^2

 What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.
