Question

Are the two figures similar? If so, give the scalefactor of the first figure to the second figure.

Answer 1

The two figures can be similar if

$\frac{b_2}{b1}=\frac{h2}{h1}$

Since b1 = 9 cm and h1 = 18 cm

Since b2 = 12 cm and h2 = 54 cm

$\frac{b_2}{b_1}=\frac{12}{9}=\frac{4}{3}$$\frac{h2}{h1}=\frac{54}{18}=3$

Since they are not equal, then the two figures are not similar

The answer is NO
