Answer:
The total distance walked by Amber = 17.63 units
Step-by-step explanation:
The given graphs shows the locations of Amber's, Betsey's and Claire's houses.
Each unit on the graph represents 1 block.
It is formed a right angle triangle.
In a right angle triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. It is called the Pythagorean statement.
Here hypotenuse represents the distance between Amber house and Claire house.
We use the Pythagorean statement and find the distance between Amber house and Claire house.
Since Distance from Claire's house to Betsey's house = 7 blocks = 7 units
and distance between Amber and Betsey's house = 8 blocks = 8 units
Distance² = 7² + 8²
= 49 + 64
= 113
Taking square root on both sides, we get
√Distance² = √113
Distance = 10.63 units
So, the distance between Amber house to Claire house = 10.63 units
Therefore, the total distance walked by Amber = 10.63 units + 7 units
= 17.63 units
