How can you decide whether a photo or drawing can be enlarged or reduced to fit a space without distorting the shape?

make sure the ratio of the dimensions stays the same. say if you had a 3 x 4 picture you could change the dimensions to 6 x 8 and because they are the same ratio the image should not be distorted.
You can make sure that the ratios of the corresponding side lengths stay the same. For example the dimensions are 2 and 4. You can then make apicture that is doubled 4 and 8. If you make this for example a square this will fitin the larger one 4 times without distorting it (distorting means twisting or rotating)
