line = 7.2 cm.
consider 5:3 as 5x and 3x.
5x + 3x = 7.2
8x = 7.2
x = 7.2/8
x = 0.9
therefore =
5x = 5 * 0.9 = 4.5
3x = 3 * 0.9 = 2.7
therefore two parts of line are 4.5 and 2.7.

the answer is given in the picture...☝☝
the measure of those two parts is...
7.2÷8=0.9
:.0.9×5=4.5cm___(1)
and..
0.9×3=2.7cm____(2)
are the measures of given two parts..
hope it helps you....
