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.

Step-by-step explanation:
Answer:
91
Step-by-step explanation:
Each term is 8 more than the last, so you can write the terms of the sequence until you get there:
11, 19, 27, 35, 43, 51, 59, 67, 75, 83, 91
__
Or, you can use the formula for the general term of an arithmetic sequence. You have first term a1=11 and common difference d=8.
an = a1 +d(n -1)
a11 = 11 + 8(11 -1) = 11 + 80
a11 = 91
