I need help solving this problem. May someone please help me.

The following information is:

Let "p" represent "The area of rectangle ABCD is 50 square inches." Let "q" represent "The perimeter of rectangle ABCD is 30 inches." Let "r" represent "The length of represent "The length of rectangle ABCD is twice the width."

The question is:

If rectangle ABCD is 9 inches long and 6 inches wide, what is the truth value of the disjunction q v ~p?

Suppose rectangle ABCD is 12.5 inches long and 4 inches wide. What is the truth value of the conditional p --> r?

Because the area is 54 then p is false. So what is the truth value of q v ~p?

For the second one recall that true implies false is false.
BUT false implies anything is true!
AND anything implies true is true!
