A gardener wants to run a border around the outside of her garden. She plots it on a grid to plan how much she will need. The garden is in the shape of a rectangle with vertices at (3, 9) (5, 9) (3, 3) (5, 3). Find the total length of border needed.

Respuesta :

Distance between (2, 5) and (8, 5) = 8 - 2 = 6Distance between (8, 5) and (8, 3) = 5 - 3 = 2Distance between (8, 3) and (2, 3) = 8 - 2 = 6Distance between (2, 3) and (2, 5) = 5 - 3= 2
Total length of border = 6 + 2 + 6 + 2 = 16
