The graph shows the location of karen’s, amanda’s, and zaley’s houses on a coordinate plane. each unit of the graph represents 1 block.

zaley is going to babysit for amanda and karen. how many total blocks will she travel if she goes to amanda’s house, then to karen’s and finally back home? round your answer to the nearest whole block.
a. 8 blocks
b. 18 blocks
c. 19 blocks
d. 27 blocks

Option C. 19 blocks

Step-by-step explanation:

From the given graph we can calculate the distances between Zaley to Amanda and Zaley to Karen in blocks so that we can apply Pythagoras Theorem in the given right angle triangle to calculate the distance between Karen and Zaley.

Distance between Amanda and Karen = 6 blocks

Distance between Amanda and Zaley = 5 blocks

Then distance between Karen and Zaley = √5²+6² = √25+36 = √61 = 7.8 ≅ 8 blocks.

Therefore Zaley travels the distance from her house to Amanda, Karen and back to her house will be = 5 + 6 + 8 = 19 blocks

So the answer is Option C. 19 blocks
