I worked this out using DX=(FA)/(LE) and found 1.48x10^⁻2, is this right?

Can I have some light?

In the elastic region, Young's Modulus = stress/strain.

Stress = Force/Area.

You're trying to work out strain. Strain = Stress/YM.

Now that you have the strain, you can work out the elongation, and then once you have the elongation you can work out the new length.
