none, she doesn't have enough wood if it is 5.25 yards and she wants to make 8 1-yard legs

Step-by-step explanation:

The complete question in the attached figure

we know that
length side AB=8 units
length side DE=4 units

[ABC]=[DEF]*[scale factor]

[scale factor ]=[ABC]/[DEF]---------> 8/4--------> 2

the answer is
the scale factor for a dilation image of DEF to obtain ABC is 2
