Question

a photo measuring 5.5 cm by 9cm is enlarged in the ratio of 7:5. find new length and width​

Answer 1

Step-by-step explanation:

Enlarging in the ratio 7:5 means that you multiply original lengths by (7/5). So 5.5

becomes (7/5)(5.5) = 7.7 and 9 becomes (7/5)(9) = 63/5 = 12.6. So new dimensions

of the picture are 7.7 cm by 12.6 cm. We cannot say which is length or width since

we were not informed which was length or width in the original dimensions.
