Question

The dimensions of Rectangle A are 6 times the dimensions of Rectangle B. How do the areas of the Rectangles compare

Answer 1

The area of Rectangle A will always be 36 times the area of Rectangle B.

For example:
If Rectangle B has length 1 and width 2, Rectangle A will have length 6 and width 12. By multiplying, Rectangle A will have an area of 72 and B 2. Divide the two numbers and you will have 36.
