Question

Rectangle ABCD is dilated by a scale factor of 3 with the center dilation at (0,0). What is the area, in square units, of resulting dilated rectangle A’B’C’D’

Answer 1

216

Explanation:

The area dilation ratio is the square of the length dilation ratio

The area of the original rectangle is 6*4=24

the length dilation ratio is 1:3

the area dilation ratio would be 1:3² which is 1:9

The resulted area=24*9

=216
