Answer: The answer is 20 inches.
Step-by-step explanation: As given in the question and shown in the attached figure, Keyley drew the rectangle 'R' and square 'S' with equal areas.
Also, the length of Keyley's rectangle 'R' = 8 inches. Let the breadth be 'b' inches. Again, let 'l' be the length of a side of square 'S'.
Then, we must have

Now, the only possible value of b is 2, so that

Thus, the breadth of 'R' is b = 2 inches and side of 'S' = 4 inches.
Therefore, perimeter of Keyley's rectangle 'R' is given by

Thus, the answer is 20 inches.
Euclid wrote 1 books related to math & logic.
He compiles all his studies in one treatise called ELEMENTS
The answer is D, since when you simplify the equation, you would sqrt each side of the equation, making the answer be the positive square root of 289.
Hope this helps!
