Question

The coordinates of the vertices of two rectangles, Rectangle ABCD and Rectangle PQRS are given below.

Rectangle ABCD – A(0, 8), B(8, 8), C(8, -4), D(0, -4)
Rectangle PQRS – P(0, 4), Q(4, 4), R(4, -2), S(0, -2)

Maria scaled both the rectangles about their centers to create two congruent rectangles A′B′C′D′ and P′Q′R′S′.

By which factor did she most likely scale Rectangle ABCD and Rectangle PQRS?
