To find the perimeter, we need to calculate the distance between each pair of points and add them up.
The distance between points A and B is 1 - (-5) = 6 units = 6 yards.
The distance between points B and C is 10 - (-12) = 22 units = 22 yards.
The distance between points C and D is 1 - (-5) = 6 units = 6 yards.
The distance between points D and A is 10 - (-12) = 22 units = 22 yards.
Adding all the distances together gives us:
6 + 22 + 6 + 22 = 56 yards
Therefore, the park needs 56 yards of fencing for the new playground.
