Q:

PLEASE HELP!!!!!!! ALSO SHOW WORKYou have enough fencing to create square pen with an area of 529 yd.2 Find the ​length of each side​ of the fence. What would be the ​perimeter​ of the square pen? If you wanted to take the fencing and create a round pen, what would be the ​diameter​ and the area​ of the round pen (Use π = 3.14 and round to the nearest ​hundredth​). Does the square pen or round pen give you the greatest area?

A:
Answer: a) 92 yards, b) 29.29 yards and 672.99 sq. yd.Step-by-step explanation:Since we have given that Area of square pen = 529 sq. ydLet the length of each side be 'a'.As we know the formula for "Area":[tex]Area=a^2\\\\529=a^2\\\\\sqrt{529}=a\\\\a=23\ yd[/tex]So, the perimeter of the square pen is given by[tex]4\times s=4\times 23\\\\=92\ yd[/tex]So, perimeter of square pen = Perimeter of round pen [tex]92=2\pi r\\\\92=2\times 3.14\times r\\\\\dfrac{92}{2}=3.14\times r\\\\\dfrac{46}{3.14}=r\\\\14.64=r[/tex]So, the diameter of round pen is [tex]2\times r=2\times 14.64=29.29\ yd[/tex]And the area of round pen is [tex]\pi r^2\\\\=3.14\times (14.64)^2\\\\=672.99\ sq.\ yd[/tex]Hence, a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
