A triangle has a height of 4 1/2 cm. and a base of 2 1/4 cm. A dilation is applied with a scale factor of 1/2. What are the measurements of the new triangle.

height = 9 cm. and base = 4.5 cm

height is 2 1/4 cm. and the base = 1 1/8 cm.

height = 2 1/2 cm. and the base = 1 1/4 cm.

height = 2 1/2 cm. and the base = 2 1/4 cm
