Question

These two triangles are scaled copies of one another the area of the smaller triangle is 9 squared units what is the area of the larger triangle?3. 6.

Answer 1

You can follow these steps:

1. Find the Length scale factor. Knowing the heights of the triangles, you can divide the height of the larger triangle by the height of the smaller triangle:

`sf=\frac{6\text{units}}{3\text{ units}}=2\text{ units}`

2. Find the Area scale factor
