Question

Metal bar is 2.4 metre long after heating it length increase by 2% what is the new length

Answer 1

Length of bar=2.4 m
Increase in length=2%
New length=(102÷100)×2.4m
=2.52 m

Answer 2

Answer:

length of metal bar= 2.4m

2% of 2.4=

$\frac{2}{100} \times \frac{24}{10}$

=

$\frac{48}{1000}$

= 0.048m

new increased length of rod

=2.4 + 0.048

=2.448m
