Ok!! for this, you can draw a right angle triangle to calculate the distance.
The bottom side's measurement will be 6 mi (because each square represents 1 mi)
The horizontal, straight side will be 5 mi (for the same reason)
Now, to find the distance from her house to the gas station, you can use the Pythagorean theorem, which states c^2 = a^2 + b^2
c^2 is the hypotenuse (always the diagonal, longest, opposite side to the right angle) It represents the distance between her house and the gas station in this case.
Now you just sub in the values to the pythagorean theorem. It's your choice whether side a or b is 36 or 25. It doesn't really matter in this case
c^2= (6)^2 + (5)^2
c^2= 36 + 25
c= square root of (36+25)
c= square root of ( 61)
c= 7.81 miles !!
