Similar Shapes: Area

# Similar Shapes: Area

### Similar Shapes: Area

Similarity means that shapes are proportional, and we can extend this idea to area as well.

As with lengths, the **area** of two similar shapes is also proportional to each other.

How do you find the scale factor for lengths in similar shapes?

If we know the area scale factor and the area of one shape, we can find the area of the other shape.

How can we find the area of a larger shape, if we are given the area of a smaller similar shape?
