Answer:
Let d represent the distance from home to school
To find d we use the formula for Pythagoras theorem
That's
a² = b² + c²
Where a is the hypotenuse or the longest side
From the question
d is the hypotenuse
So we have
d² = 4² + 5²
d² = 16 + 25
d² = 41
d = √41 miles or 6.403 miles
Hope this helps you
