A photographic negative is 2 in. by 1.5 in. An
enlarged print from this negative has a length
of 9 in. as its shorter side. What is the length of
its longer side?


Sagot :

Answer:

The length of the longer side is 12 in

Step-by-step explanation:

Scaling

The dimensions of the photographic negative are 2 in by 1.5 in.

An enlarged print of it has a length of 9 in and it's equivalent to the shortest side.

Since the shortest side of the negative is 1.5 in, the scale factor is 9/1.5 = 6.

The longer side should have been enlarged by the same factor, thus the longer side is 2*6 = 12 in

The length of the longer side is 12 in
