Step-by-step explanation:
Unit 19 Section 3 : Line, area and volume scale factors
In this section we look at what happens to the area of shapes and the volume of solids when the lengths in those shapes or solids are enlarged by a particular scale factor. The examples below will explain further.
Example 1
Consider a rectangle 5cm by 2cm.The area of the rectangle is 5cm × 2cm = 10cm², but what happens if the rectangle is enlarged?
