When you are finding the area, you multiply the length x the width. So for example, we have a rectangle that the length is 6 feet and the width is 4 feet. So, first of all we multiply 6x4= 24. Since its area don't forget it is Square Feet (or any other type of measurement).

Answer:
a) h∧¬r→s
b) r→¬s
c) s→h
c) s→¬r
Step-by-step explanation:
a) The sufficient condition for "I will go swimming" is "it's hot and not raining" . With your variables, the sufficient condition for s is h∧¬r. Then, if h∧¬r is true, s will be true, which means that h∧¬r implies s.
b) This means that the only thing that would stop you from go swimming is that its raining. Then, if it rains, you won't go swimming, that is, r implies ¬s.
c) It is necessary (it must happen) that it is hot for you to go swimming. Then, it you are swimming, it must be hot (otherwise you wouldn't be swimming), hence s implies h
d) Just as in c), if you go swimming, it must not be raining. Then s implies not r.
Some final comments. Suppose you have the implication p→q. Then, it is equivalent to say:
- p is sufficient for q (If p then q)
- q is necessary for p (p only if q)
