Answer:
The answer is p = 16
Explanation:
Since the triangles are similar it means that there is a scale factor between triangle FHG and triangle DFE. Dividing either length of the known sides of triangle DFE by the corresponding sides of triangle FHG will give the scale factor which turns out to be 1 and 1/3. Multiplying the length of side FH by the scale factor (1 and 1/3) will give the length of side DF, or p, since side FH corresponds to side DF. Multiplying side FH by the scale factor will give an answer of 16. Therefore, side DF, or p, is equal to 16.
