Given:

Triangle EFG is similar to triangle HIJ.

To find:

The measure of side IJ.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Triangle EFG is similar to triangle HIJ.

$\dfrac{EF}{HI}=\dfrac{FG}{IJ}$

Putting the given values, we get

$\dfrac{7}{32}=\dfrac{4}{IJ}$

$7\times IJ=4\times 32$

$IJ=\dfrac{128}{7}$

IJ=18.2857

$IJ\approx =18.3$

Therefore, the measure of side IJ is 18.3 units.
