20%
=0.2
0.2*650

What are we trying to solve?
Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.

Answer:
<em>A = 32²cm</em>
Hope this helped!
Step-by-step explanation:
<h3>A = lw/2</h3>
<u>We know that the width is 8cm, and that the length of the rectangle and triangle combined is 14cm.</u>
<u />
How we find the length of the triangle itself is 14cm - 6cm, since 6cm is the rectangles length (which we know because it gives it to us at the top!)
14cm - 6cm = 8cm
<h3>Now we can plug into our formula and solve</h3>
A = 8(8)/2
A = 64/2
<h3><em>A = 32²cm</em></h3>
