Answer:
-25
Step-by-step explanation:
For side length s, the area of a square is given by
... A = s²
Then the side length can be found to be
... s = √A = √(506.25 ft²) = 22.5 ft
The perimeter is the sum of the lengths of the four equal sides.
... P = 4s = 4·(22.5 ft) = 90 ft
Stevan will need 90 ft of fence to complete the job.
<span>Let the distance a string will stretch be l, and the weight attached to the string be w, then l = kw. 9 = 100k => k = 9/100. l = 9/100 w. Therefore, when a weight of 90 pounds is attached, l = 9 / 100 x 90 = 810 / 100 = 8.1 inches.Hope I helped! :) Cheers!I hope that I could help :) sometines those questions are tricky. Let me know if you need additional help</span>
