$a b$ $ab$ means product of $a$ $a$ and $b$ $b$ , not merely placing the given digits 3 and 4.

$therefore ab = 12$

K= ab+c/2

a=3
b=4
c=6

$K = ab + c/2$

Apply BODMAS rule:

$K = 3\times 4 + 6/2$

$K = 12 + 3$

$K =15$

Value of $ab = 12$

In the expression, $ab$ means product of $a$ and $b$ , not merely positioning the given digits 3 and 4.
