Answer:
The upside down V symbol is known as a wedge. It represents a conjunction which is informally the "and". In other words,
Note how we can replace p with "the taxes are high" and replace q with "the job pays well" to arrive at the overall compound statement "The taxes are high and the job pays well".
Some logic textbooks will use an ampersand symbol & to be used in place of a wedge. It will depend on the notation that they, or your teacher, has set up.
Remember that the area of a rectangle is length times width; since we don't know the width, we'll use the Pythagorean theorem to find it first:
Where l is the leg, and h the hypotenuse. We know that one of the legs, the base has a measures 34.3 inches and the hypotenuse a measures 42.1 inches.
Replace the values to get:
Now that we know the width (w), we just net to multiply it by the length to get our area:
We can conclude that the correct answer is <span>B) 836.9 in.</span>
