Question

The location of four buildings on a coordinate grid are as follows:

Building 1 is at (−5, −3).

Building 2 is at ​ (−5, 5).

Building 3 is at (4, 5).

Building 4 is at (4, −3).

A bike courier begins at building 1 and then delivers packages to building 2, then building 3, and then building 4. Then she bikes back to building 1. The path between each building is a straight line. One unit on the coordinate grid equals 100 feet.

What is the total distance the courier biked?

Enter your answer in the box.

Answer 1

Answer: 3400 feet

Explanation:

Answer 2

3400 feet

Explanation:

Distance between building 1 and building 2 = |5+3| = 8

Distance between building 2 and building 3 = |4+5| = 9

Distance between building 3 and building 4 = |-3-5| = 8

Distance between building 4 and building 1 = |4+5| = 9

total distance = 8 x 2 + 9 x 2 = 34

total distance in feet = 34 x 100 = 3400 feet
