Answer:
264 ft²
Step-by-step explanation:
The right triangle shown at the right end of the figure has a missing leg that can be found using the Pythagorean theorem. (If you recognize the triangle as a 5-12-13 triangle, you already know its length is 12 ft.)
a² +b² = c²
5² + b² = 13²
b² = 169 -25 = 144
b = √144 = 12
So, the height of the parallelogram is 12 ft, and its base length is 22 ft. The area is the product of these ...
A = bh = (22 ft)(12 ft) = 264 ft²
Answer:

Step-by-step explanation:
Hi!
So let's write the equation again

The next step is to plug in known values:

Now we solve this as a normal algebra equation:
Do same to both sides


I hope this helped. Let me know if you have any questions
The answer is C because when you divide it out you get 6
the square is the only quadrilateral that has only all the same sides with the equal lengths and angles
