determine the contrapositive of the conditional statement: lengths of the sides of a rectangle are 6 inches and 4 inches, the area is 24 square inches

OpenStudy (mertsj):

Can you form the converse?

OpenStudy (mertsj):

Because the contrapositive is just the converse with both parts negated.

OpenStudy (anonymous):

well the answers are either a) if the lengths of the sides of a rectangle are not 6 inches and 4 inches then the area is not 24 square inches. b) if the area is 24 square inches, the the lengths of the sides of a rectangle are not 6 inches and 4 inches. c)if the area is not 24 square inches then the sides of a rectangle are not 6 and 4 inches d)if the area is not 24 square inches, then the lengths of the sides of a rectangle are 6 inches and 4 inches

OpenStudy (dumbcow):

you have --> p implies q the contrapositive is --> not q implies not p

OpenStudy (anonymous):

what??

OpenStudy (mathstudent55):

Statement: If p, then q. Converse: If q, then p. Inverse: If not p, then not q. Contrapositive: If not q, then not p. Statement: If (hypothesis), then (conclusion). Converse: If (conclusion), then (hypothesis). Inverse: If (not hypothesis), then (not conclusion). Contrapositive: If (not conclusion), then (not hypothesis). In your case the original statement is: If the lengths of the sides of a rectangle are 6 inches and 4 inches, then the area is 24 square inches. A statement is: If (hypothesis), then (conclusion). That means in your case: hypothesis = the lengths of the sides of a rectangle are 6 inches and 4 inches conclusion = the area is 24 square inches For the contrapositive, you interchange the hypothesis and the conclusion, and you also negate both.
