1. so the scale factor is 5 to 3 or 5/3.....a scale factor is what u multiply the first shape by to get the second shape

so if FH = 45....and a scale factor of 5/3 is applied, then NP = (45 * 5/3) = 75
=================
so BDFH has a scale factor of 3/4 applied to get  MOQS
so MO = BD * 3/4.......MO = 48 * 3/4 = 36
=================
notice that the small triangle is 1/3 of the larger triangle....so the area would be 1/3 of the larger triangle
So if larger triangle has an area of 567, then the smaller triangle would have an area of (567/3) = 189 cm^2 <==
=================
the smaller triangle is 1/6 the size of the larger triangle...so if the larger triangle has an area of 270, then the smaller triangle has an area of 
(270/6) = 45 cm^2 <==
1) D. 75

[tex]45 \times \frac{5}{3} = 75[/tex]

2) B. 36

[tex]48 \times \frac{3}{4} = 36[/tex]

3) D. 189 cm ^ 2

K= copy over the original (K= scale factor)

[tex] \frac{18}{54} = \frac{1}{3} [/tex]

The scale factor is 1 to 3.

[tex]567 \times \frac{1}{3} = 189[/tex]

4) D. 45 cm ^ 2

K= copy over the original (K= scale factor)

[tex] \frac{5}{30} = \frac{1}{6} [/tex]

The scale factor is 1 to 6.

[tex]270 \times \frac{1}{6} = 45[/tex]
