Answer:
Li Ping's statement makes sense.
Step-by-step explanation:
The area of a square with side lengths a inches is given by,  .
.
Now, the area of a parallelogram with equal sides a inches, which is not a square is given by,  , where, h is the perpendicular distance between the opposite sides.
, where, h is the perpendicular distance between the opposite sides. 
See the diagram attached.
Since a is the hypotenuse of as right triangle with height h, hence, a > h.
So, 
Therefore, Li Ping's statement makes sense. (Answer)
 
        
             
        
        
        
Answer:
The correct figure is B. 
Step-by-step explanation:
The statement provided is:
"If it is an equilateral triangle, then it is an isosceles triangle"
The contra-positive of a statement is determined by switching the hypothesis and conclusion of the provided statement and negating both.
Then the contra-positive of the statement provided will be:
- Switching the hypothesis and conclusion:
         If it is an isosceles triangle - It is an equilateral triangle.
- Negating both the statements:
         If it is not an isosceles triangle - it is not an equilateral triangle.
Thus, the contra-positive of the statement is:
"If it is not an isosceles triangle, then it is not an equilateral triangle."
Thus, the correct figure is B.
