I can’t see the image you mentioned. To answer exactly I need the side lengths or the original area from the figure — please re-upload the image or type the rectangle dimensions.
General method:
- Find the original area = area(rect1) + area(rect2).
- A dilation by factor 3 multiplies all lengths by 3 so areas multiply by 3^2 = 9.
- Dilated area = 9 × (original area).
If the original composite area is 45 square units, the dilated area would be 9 × 45 = 405 square units.
