<span>The difference of the vectors; sample: the other diagonal would be the sum of one of the vectors and the opposite of the other vector, so it would be the difference.

Because these are not like terms, they cannot be combined. The variables are different, that's what makes them not like terms
2pt=1qt
1pt=1/2qt
therefor
multiply 2 and 3/4 by 1/2
(2 and 3/4) times 1/2=(2+3/4) times 1/2=2 times 1/2+3/4 times 1/2=2/2+3/8=1+3/8=1 and 3/8 pt
All of the surfaces are rectangular
