How Is Displacement Calculated in a Shear Strain Scenario?

[asleight]

Homework Statement

A square steel plate is 10.0cm on a side and 0.500cm thick.

Find the shear strain that results if a force of magnitude 9.0*10^5 is applied to each of the four sides, parallel to the side.

I found the shear strain to be 2.4*10^-2

Find the displacement x in centimeters.

The Attempt at a Solution

I know that strain is displacement over length... But, is that what it's asking? Where would it be displaced if all of the sides take the pressure? And what would the initial length be?
