Answer:

320 in²

Step-by-step explanation:

Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:

Square of scale factor of the side = scale factor of area

4² = scale factor of area

16 = scale factor of area

Multiply the original area by 16

20 × 16 = 320 in²
