Its 16 units!
I did thee test on edge 🙂
Length of side QR is 16 units.
Given that dimensions of are as follows:
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.
