Question

Rectangle A measures 12 cm by 3 cm.

1. If Rectangle B was scaled copy one third the size, what would the measurements be?

2. If Rectangle B was a scaled copy double the size, what would the measurements be?

Answer 1

Answer:

1)if the rectangle B scaled copy one third of the size of rectangle A

the size of the rectangle =12by 3

=12×3 :3×3

=36 by 9

if the rectangle B scaled copy double to the size of rectangle A

The size of the rectangle A=12by3

if double the size =12by 3×2

=12×2 by 3×2

=24 by 6
