Answer:
Height: [tex] 3 in \times \frac{1}{2} = 1\frac{1}{2} in [/tex]
Width: [tex] 1\frac{1}{2} in \times \frac{1}{2} = \frac{3}{4} in [/tex]
Step-by-step explanation:
All she needs to do is to multiply each dimension of the original door image by the scale factor, to get the height and width of the scale drawing.
Height:
[tex] 3 in \times \frac{1}{2} = \frac{3 \times 1}{2} = \frac{3}{2} = 1\frac{1}{2} in [/tex]
Width:
[tex] 1\frac{1}{2} in \times \frac{1}{2} = \frac{3}{2} \times \frac{1}{2} = \frac{3 \times 1}{2 \times 2} = \frac{3}{4} in [/tex]
