Question

Rectangle Q has an area of two square units. Thea drew a scaled version of rectangle Q and labeled it rectangle R. what scale factor did Thea use to go from rectangle Q to rectangle R?

Answer 1

6

Explanation:

The area of a polygon created with a scale factor of xxx is x^2x

2

x, start superscript, 2, end superscript times larger than the original polygon:

\text{scale factor}^2=\text{how many times larger area of scale copy is}scale factor

2

=how many times larger area of scale copy iss, c, a, l, e, space, f, a, c, t, o, r, start superscript, 2, end superscript, equals, h, o, w, space, m, a, n, y, space, t, i, m, e, s, space, l, a, r, g, e, r, space, a, r, e, a, space, o, f, space, s, c, a, l, e, space, c, o, p, y, space, i, s

The area of Rectangle RRR is 363636 times greater than the area of Rectangle QQQ. Let's substitute 363636 into the equation to find the scale factor.

?^2=36?

2

=36question mark, start superscript, 2, end superscript, equals, 36

The scale factor is 666.

Hint #33 / 3

Thea used a scale factor of 666 to go from Rectangle QQQ to Rectangle RRR.
