Dividing rod

The 3m long rod should be divided into two parts so that one is 16cm longer than the other. Find the lengths of both parts.

Correct answer:

a =  1.58 m
b =  1.42 m

Step-by-step explanation:

x=3 m y=16 cm m=16:100  m=0.16 m  a=2x+2y=23+2254=5079 m=1.58 m
b=2x2y=232254=5071=1.42=5071 m=1.42 m   Verifying Solution:   A+B=x A=y+B A+B=3 A=0.16+B  A+B=3 AB=0.16  Row2Row1Row2 A+B=3 2B=2.84  B=22.84=1.42 A=3B=31.42=1.58  A=5079=1.58 B=5071=1.42
