A rectangle with an area of 4/7 m² is dilated by a factor of 7. What is the area of the dilated rectangle? Do not leave your answer as a fraction.

The area is increased by a square of the scale factor
 Calculating the area we have:
 (4/7)*7^2 =
 (4/7)*49
 (49/7)*4 =
 7*4=
 28 m^2
 answer:
 the area of the dilated rectangle is 28 m ^ 2
