Can anyone help me with Applying Scale Factors to area?

Answer 1

Step 1:Find the linear/length scale factor.
In general to find the scale factor we divide the large quantity with the small quantity. area and volume scale factor-10
Step 2:Find the Area scale factor by squaring the linear scale factor
area and volume scale factor-11
Step 3:Multiply the area scale factor with the small area to find the area for the large triangle.
area and volume scale factor-12 The area for the large shape is 27cm2
To find one of the lengths given the areas you will need first find the area scale factors and then square root it to find the scale factor. You would then multiply if finding a length for a large shape or divide if finding the length for a small shape.

hope it helps.
