Answer:
28 ft
Step-by-step explanation:
Let longer side of rectangle be
and the shorter side be
, thus we can write the ratio:

<em>Now putting 21 into S, we solve for L:</em>

Hence, length of longer side is 28 ft.
Correct answer:
19.7ft
Explanation:
This problem is solved using the Pythagorean theorem (a2+b2=c2). In this formula a and b are the legs of the right triangle while c is the hypotenuse.
Using the labels of our triangle we have:
o2+a2=h2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h2=100ft2+289ft2
h=389ft2−−−−−√
Correct Answer →19.7ft
Hope this helps!

The answer
mathematics rules tell that
if A and B are two statements that are equivalents, that is also called biconditional statement, or " if and only if " statement
the general signification of <span>biconditional statement and its converse is:
if A, then B and if B then A (the converse), A and B are equivalent statements
</span><span>["If a natural number n is odd, then n2 is odd" and its converse ] does mean
</span><span>A natural number n is odd if and only if n2 is odd.
the answer is B</span>
Answer: A
