Question

Can someone help me with this question? It is either a whole number or a fraction. No decimal or mixed fraction!

Answer 1

3

Explanation:

Well, both triangles are equilateral so all sides measure the same. Because of this, we can determine the scale by seeing how much the first triangle is different from the second.

3 x 3 = 9, so therefore the triangle tripled in size.

Hope this was helpful!!
