Question

Rectangle A measures 9 inches by 3 inches. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.

Answer 1

Answer:

3 inches by 1 inches or 6 inches by 2 inches. Both answera are correct

Step-by-step explanation:

just an equivalent ratio

Answer 2

The measurement pairs that could be the dimensions of Rectangle B are;

• 6in by 2in
• 3in by 1in

The scaled copy of a shape is derived if the original figure is dilated by a constant

Given the measure of the sides of rectangle A:

Length = 9in

Width = 3in

Get the dilation factor

Dilation factor k = ratio of the sides

k = 9/3

k = 3

This means that rectangle B must also have the same scale factor as A.

The possible dimension pairs are 6in by 2in and 3in and 1in since the ratio of their sides is also 3;

k = 6/2 =3

k = 3/1 = 3
