Answer:
See explanation below.
Step-by-step explanation:
The scale factor can be found by dividing two corresponding side lengths. For instance, if you have two triangles, divide the new length of the larger or smaller triangle by the same side length of the original.
If the side length of the new was 9 and the old was 3 then the scale factor would be 9/3 = 3.
If it were flipped then the new would be 3 and the old would be 9. So the scale factor would be 3/9 = 1/3.

Answer:
48.25
Step-by-step explanation:
When finding an area of a triangle it is area = base times height divided by 2.
AKA a =bh1/2
We can do that for all sides in this equation.
For the bottom we can do:
5*4.3=21.5 21.5/2 = 10.75
For one side we can do:
5*5 = 25 25/2 = 12.5
12.5 = one side, but there are three so,
12.5*3 = 37.5
37.5 + 10.75 = 48.25
