Difference between "sq km" and "km sq"
By Michael Henderson •
If I have a square with side $2\ \text{km}$, what is its area: $2\ \text{sq km}$ or $4\ \text{km}^2$?

$\begingroup$A square with side $2\ \text{km}$ has area $4\ \text{km}^2$. This is pronounced as four square kilometres.
$\endgroup$ $\begingroup$Suppose that a triangle has $\text{height = }a \text{ cm}, \text{ base = }b \text{ cm}$. The area, in mathematical notation, is $\Large {a\cdot b \over 2} \normalsize \text{cm}^2 $.
You may pronounce the above as the quantity a times b all over two square centimeters, even though there is no difference at all.
