This is the concept of scale factors. Given that Joaquin has reduce the dimensions of a picture by scale factor of 0.3 and the original dimension was 10 cm length by 10 cm width, the new dimension will be: New length=(old length)×(scale factor) New width=(old width)×(scale factor) Plugging the values in the above formulas we get:
