Arectangular park that measures 245 yards by 420 yards has a sidewalk around it. what is the least distance a person must walk to go around the park once?

It will take someone 1,330 yards to walk around it once because a rectangle has 4 sides and 2 of those sides are equal. So 420 x 2=840, and 245 x 2=490, and if you add those you get 1,330 and that is how many yards it takes to walk around the park once.

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.
