Scaled Copies

A scaled copy is a figure that is similar to the original figure but is a different size, created by multiplying all dimensions of the original by the same scale factor.

The scale factor is the number you multiply the original shape by in order to get the scale copy.

To find the area of a rectangle, multiply its length by its width.

The area is 24 sq cm (6 cm x 4 cm).

Yes, if all corresponding lengths are in the same ratio, then Figure B is a scaled copy of Figure A.

The area of the shape increases by a factor of 4 (2 squared) because area is a two-dimensional measurement.

The dimensions of a scaled copy are found by multiplying the original dimensions by the scale factor.

The original figure is reduced to half its size.

Area = length x width.

The area is 25 sq cm (1/2 x base x height = 1/2 x 10 cm x 5 cm).
