Complete the indirect proof.

Given: Rectangle JKLM has an area of 36 square centimeters. Side is at least 4 centimeters long.
Prove: KL ≤ 9 centimeters

Assume that a. ____. Then the area of rectangle JKLM is greater than b. _____ , which contradicts the given information that c. _____. So the assumption must be false. Therefore, d. _____.

im just not sure how to answer this question, or how to even start it
If the sides are x and y, then we have

xy = 36
y = 36/x

So, let x=4. Then y = 36/4 = 9

Now, you know that dividing by a larger value gives a smaller quotient.

So, x>4 means y<9
