$Distance = 15\ miles$

Explanation:

Given

$North = 12\ miles$

$East = 9\ miles$

Required

Distance from her house to the store

If she drive straight from her house to the store, this would form a right angled triangle;

Where the horizontal line would be:

$North = 12\ miles$

And the vertical line;

$East = 9\ miles$

And the required distance would be the hypothenuse of the triangle;

Using Pythagoras, we have:

Distance^2 = 9^2 + 12^2

Distance^2 = 81 + 144

Distance^2 = 225

Take square root of both sides

$Distance = 15\ miles$
