Based on the directions we know that both figures are similar, meaning there is a dilation factor changing the overall size of the figures. In order to find this dilation factor we can give it the value of x and multiply it to the various lengths of the smaller figure. Once this is done, we make these values equal to their the corresponding counterparts on the larger figure.
32x=40
x=5/4
Now that the dilation factor is found substitute its value for x
