a father wants to build an octagonal (that is, 8-sided) play pen for his toddler. each side of the octagon has a length of 3sqrt{50} inches. what is the perimeter of the octagon? *recall that the perimeter is the sum of each side of a shape boundary a. 3sqrt{400} inches b. 24sqrt{2} inches c. 120sqrt{2} inches d. 23sqrt{400} inches

Answer 1

perimeter =
`8(3 √(50) )=24 √(25 * 2) =24 * √(25) * √(2) =24 * 5 √(2) =120 √(2)`
