When deriving the distance formula, eowyn starts with two points, a(x1,y1) and b(x2,y2). she then draws point c on a horizontal line from point a and a vertical line from point b, giving it coordinates (x2,y1). in doing so, she believes she created a right triangle, with right angle c, which allows her to use the pythagorean theorem. she lets ac=b and bc=a, which means that ab=c by definition of the hypotenuse.
next, she uses the ruler postulate to state that a=|x2βx1| and b=|y2βy1|. then, combining this information with the pythagorean theorem, she is able to use the substitution property of equality to state that (x2βx1)2+(y2βy1)2=ab2. finally, she applies the square root property of equality to find ab=(x2βx1)2+(y2βy1)2β. she is able to ignore the possible negative root since distance is always positive, by definition.
which statement about eowyn's derivation is the most accurate?

Suppose that one doll house uses the 1 inch scale, meaning that 1 inch on the doll house corresponds to 1/2 foot for life-sized objects. if the doll house is 108 inches wide, what is the width of the full-sized house that it's modeled after? in inches and feet.
