Indirect proof ! will medal

given: rectangle jklm has an area of 36 square centimeters. side is at least 4 centimeters long.
prove: kl ≤9 centimeter

"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 area of the rectangle:
A = Length x Width = JK x KL = 36 cm²
If JK ≥ 4 cm, we have to prove that KL ≤ 9 cm.

Assume that a. KL > 9 cm.
Then the area of rectangle JKLM is greater than b. 36 cm²,
which contradicts the given information that c. side is at least 4 cm long.
So the assumption must be false. Therefore, d. KL ≤ 9 cm.
