Answer: The distance is 214.7 meters
Step-by-step explanation: Please refer to the picture attached for details.
The coordinates given shows that Francesca's house lies at the point (10,20) and the distance to the right is also at the point (200,20), and this point which we shall call B is actually measuring 190 meters. Francesca's house at point H is located at 10 units on the x-axis, while point B is located at 200 units on the x-axis. Hence the actual measurement is 200 - 10 which equals 190 units (or 190 meters).
Similarly, Camp Sunshine or point C lies on (200,120) which makes it located at 120 units on the y-axis, and point B which lies on (200,20) is located at 20 units on the y-axis. This makes the distance from point B to point C measure as 120 - 20 which equals 100 units.
Using the Pythagoras' theorem, which states that AC² = AB² +BC², where AC is the hypotenuse (longest side),
The distance from her house to camp sunshine is given as
HC² = HB² + CB²
HC² = 190² + 100²
HC² = 36100 + 10000
HC² = 46100
Add the square root sign to both sides of the equation
√HC² = √46100
HC = 214.7091
HC ≈ 214.7 (to the nearest tenth of a meter)
Therefore the distance between Francesca's house to camp sunshine is 214.7 meters
