If a two-dimensional shape is dilated by a factor of 1/3, what is the effect on the area?(1 point)

Responses

It is 1/3 as great.
It is Start Fraction 1 over 3 End Fraction as great.

It is 1/6 as great.
It is Start Fraction 1 over 6 End Fraction as great.

It is 2/3 as great.
It is Start Fraction 2 over 3 End Fraction as great.

It is 1/9 as great.

The correct answer is "It is 1/9 as great." When a shape is dilated by a factor of 1/3, the area is reduced by a factor of (1/3)^2, which is equal to 1/9.
