Barney has to run some errands around town. Look at the map below to calculate his distance if he starts at home, goes to the video store, then the grocery store, grabs a fast snack, and ends at home. How many units did he walk?

Coordinate grid with points labeled home, video store, fast snacks, and grocery store. Home is located at (-3, 4), video store is at (4, 4), fast snacks is at (-3, -3), and grocery store is at (4, -3).

Group of answer choices

14 units

21 units

28 units

35 units

Correct answer is option C = 28 units

Step-by-step explanation:

From the question, we are given the coordinate grid of each location and point of Barney's stops, He starts at home, then goes to the video store, then grocery, then fast snacks and back home:

From home to video: (-3, 4) to (4, 4) -is x = 4 - (-3) = 7 units. (y is 4 - 4 = 0)

So, distance of 7 units east (right)

From video to grocery: (4, 4) to (4, -3) - is y = -3 - 4 = -7 units. (x is 4 - 4 = 0)

So,distance of 7 units south (down)

From grocery to snacks; (4, -3) to (-3, -3) - is x = -3 - 4 = -7 units. (x is -3 - (-3) = 0)

So, distance of 7 units west (left)

From snacks to home (-3, -3) to (-3, 4) - y = 4 - (-3) = 7 units. (x = -3 - (-3) = 0)

So, distance of 7 units north (up)

In summary, Barney made a square shape with an equal distance of 7 units between all his four stops for a total distance of:

7 + 7 + 7 + 7 = 28 units
