Question

Rectangle A measures 9 in by 3 in rectangle b is a scaled copy of rectangle A select all of the measurent paris that could be the dimesnions of rectangle b

Answer 1

the options are missing, so I looked for a similar question:

• 4 inches by 3 inches
• 3 inches by 1 inch
• 6 inches by 2 inches

the correct options are:

3 inches by 1 inch

6 inches by 2 inches

A scaled copy means that the values of rectangle A are related to the value of rectangle B by a scaling factor. In this case, the scaling factor is 3:1. This means that for every 3 inches in rectangle A, you will have 1 inch in rectangle B.

E.g. imagine that instead of making the rectangle smaller, you would make it larger. Using the same scale 3:1, rectangle B could be 30 inches by 10 inches, or 600 inches by 200 inches.
