Answer:
Length of side QR is 16 units.
Explanation:
Given that dimensions of
are as follows:

Side QP

Side PR = 8 units
To find, side QR = ? units
Please refer to the attached figure for the representation of the given dimensions.
Base is side QP,
Perpendicular is side PR and
Hypotenuse is side QR.
In a right angled triangle, Pythagorean theorem holds true i.e.
Accoring to pythagoras theorem:


Putting the values of QP and PR:

So, the value of length of side QR is 16 units.
