Using proportions, it is found that the length of MN is of 48 inches long.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

MP = 8 and PN is 5 times as long as MP, hence:

PN = 5 x 8 = 40.

Then:

MN = MP + PN = 8 + 40 = 48 inches long.
