can't help with the illustration. But use the Pythagorean theorem to solve the algebra part.
You are given two sides of a right triangle and asked to find the third side. In the case, that third side is the hypotenuse.
a%5E2+%2B+b%5E2+=+c%5E2
20.5%5E2+%2B+8%5E2+=+c%5E2
420.25+%2B+64+=+c%5E2
484.25+=+c%5E2
sqrt%28484.25%29+=+c+
22.001+=+c Your answer is in meters
