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.
X= 26
The equation is setup like 2x+10=62 because the angles are the same
When you see a formula like this, try to operate, so you will see some identities sooner or later. In this case, we have a substraction identity:
=
=
1 + tan α · tan β
