Diagonal:

(16^2 + 26^2)^(1/2)

= (256 + 676)^(1/2)

= 932^(1/2)

= 2 sqrt 233

= 30.5286750449...

Square 16 and Square 26. Now add the two and take the Square Root.

256 + 676 = 932

Square Root of 932 = 30.5

16" = 40.64 cm, 26" = 66.04 cm

diagonal = square root (40.64^2 + 66.04^2) = 77.54 cm^2

I don't know how to calculate it in caveman units though.

I assume that you want the length of the diagonal of a rectangle that is 16" x 26".

diagonalsquared = 16squared + 26squared

Just use a calculator
