- We'll learn that you can use a scale factor to make lengths bigger or smaller.
- We will also learn how to use a scale factor to make scale drawings of geometric shapes.
- And we'll see how this knowledge can help us design a T-shirt, make a poster, and even build a car!
A rectangle has base 5 cm and height 11 cm. Use a scale factor of 2 to find a new rectangle’s dimensions.
A triangle has side lengths 30 cm, 40 cm, and 50 cm. Use a scale factor of [ggfrac]1/2[/ggfrac] to find a new triangle’s dimensions.
On a coordinate grid, a rectangle’s coordinates are C(0, 0), A(6, 0), T(6, 12), and S(0, 12). Find the area of a new rectangle made with a scale factor of [ggfrac]1/3[/ggfrac].
