Question

The location of four buildings are on a coordinate grid are as follows: bank at (3, −3) post office at (−2, −3) ​​ dry cleaner at (−2, 6) pizza shop at (3, 6) Liza begins at the bank and then walks to the post office, then to the dry cleaner, and then to the pizza shop. Then she walks to the bank again, where she left her cell phone. The path between each building is a straight line. One unit on the coordinate grid equals 400 yards. What is the total distance Liza walked?

Answer 1

11,200 yards

Explanation:

First, plot all the points on a graph. Then draw Liza's path. Add them all up and multiply by 400.

28 · 400 = 11,200.

Liza walked 11,200 yards.

My graph is attached. The blue line is Liza's path and each coordinate point is labeled.

I hope this helps u!!

Answer 2

11,200 yards.

Explanation:

Distance between two points is;

Distance = √(x²+y²)

Distance between Bank and post office = √(5²+0)

= 5

Distance between post office and dry cleaner = √(0+9²)

= 9

Distance between Dry cleaner and pizza shop = √(0+5²)

= 5

Distance between Bank and pizza shop = √(9²-0)

= 9

Total distance = 5+9+5+9

= 28 units

1 unit ⇒ 400 yards

28 units ⇒ (28×400)

⇒ 11,200 Units
