Answer:

B. 31.62

Step-by-step explanation:

First, find the distance of the line using the distance formula, $d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }$ . Plug the two points (-1,0) and (5,2) into the formula and solve. This gives you 6.32, then this is only one line of a pentagon, which has 5 sides, so you need to multiply. Since you are finding the perimeter, which is all of the sides added together, multiply the one side by 5. 6.32*5=31.62.
