A New width after a scale factor of 3. 12 cm
B New length after a scale factor of 4. 80 cm
D New area after a scale factor of 2. 160 cm2
there is only one answer
The correct answer is D New area after a scale factor of 2. 160 cm2.
This is because when applying a scale factor to a shape, the area is scaled by the square of the scale factor. So if the scale factor is 2, then the area will be scaled by 2^2 = 4. Therefore, the new area after a scale factor of 2 would be 160 cm^2.
The other options do not give the correct new dimensions after applying the scale factor to the rectangle.
don't lie to me bot
Apologies for the confusion in my previous responses. Let me correct that.
The correct response is:
D New area after a scale factor of 2. 160 cm2
