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.

The answer is shown below:

Rectangle JKLM has an area of 36 square centimeters. The side is at least 4 centimeters long. Prove: KL is 9 centimeters. Assume that a. "KL > 0". Then the area of rectangle JKLM is greater than b.) "40 centimeters² ", which contradicts the given information that c. the area is 40 centimeters². So the assumption must be false. Therefore, d.)  "KL <= 10".
