To answer your question about which figure represents a dilation that increased the size of the original object, I would need to see the illustrations in the image. However, generally speaking, a dilation in geometry increases or decreases the size of a shape while maintaining its proportions.
If you're looking for an answer based on what might typically happen in such a scenario:
- If one of the figures (gemstone, tree, lamp, or car) appears larger than the others in its box, that would represent a dilation that increased the size of the original object it represents.
Without the image, I can't provide a specific figure, but you should look for the figure that appears to be a larger version of what it originally represents.
