If the scale factor is 1/5, that means the original triangle would have dimensions 5 times larger than the current model. So if the current base is 5 units in size, the original triangle would be 5 times larger. 5 x 5 = 25 Units The answer is D.

Answer:

the answer is the option D [tex]25[/tex]

Step-by-step explanation:

Let

x-----> the measure of the base reduced triangle

y-----> the measure of the base original triangle

we know that

The scale factor is equal to

[tex]scale\ factor=\frac{x}{y}[/tex]

In this problem we have

[tex]scale\ factor=\frac{1}{5}[/tex]

[tex]x=5\ units[/tex]

Substitute and solve for y

[tex]\frac{1}{5}=\frac{5}{y}[/tex]

[tex]y=5*5=25\ units[/tex]
