Pls help me with my homework

Any number larger than 10 units (in my example, 30 units)

Step-by-step explanation:

A scaled copy of a shape means that all the angles are the same and that it is basically the same shape that has been made bigger or smaller but still with the same proportions.

Note: If the scale factor is greater than 1, it means that Iria's scaled copy will be larger than this triangle.

Step 1.

Choose any number larger than 1 (as we aren't given the actual number she chose). To make things easy, I will choose the number 3 as it's a small number and it's a whole number (not a fraction or decimal).

Step 2.

Take the number you chose before (in my case, 3) and multiply it with the base length of the triangle in the diagram.

10 x 3 = 30 units

Note: Since the scale factor could be any number larger than 1, the base length can be any number larger than 10.

I hope this helps! :)
