If a triangle’s original dimensions are 24 cm by 40 cm, which triangle would be an enlargement of the original by a scale factor of 2.2?

We have that
a triangle’s original dimensions are 24 cm by 40 cm
scale factor=2.2
then
a triangle’s enlargement dimensions=[scale factor]*original dimensions

a triangle’s enlargement dimensions=[2.2]*24> 52.8 cm
a triangle’s enlargement dimensions=[2.2]*40> 80 cm

the answer is
a triangle’s enlargement dimensions will be 52.8 cm by 80 cm

It should be a or d i’m not sure
