Li Ping says a square with 3 inch sides has greater area than a parallelogram that is not a square but has sides that have the s
Kipish [7]

Answer:

Li Ping's statement makes sense.

Step-by-step explanation:

The area of a square with side lengths a inches is given by, A_1 = a^{2}.

Now, the area of a parallelogram with equal sides a inches, which is not a square is given by, A_2 = ah, 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, A_1 > A_2

Therefore, Li Ping's statement makes sense. (Answer)
