# Give an example of a number that can be expressed as a rectangle as well as a square. Show the arrangement also.

**The numbers that can be expressed as a rectangle as well as a square:**

- Given non-negative integers
m and n. m and $n$, not necessarily distinct, **Rectangular numbers**are numbers of the form$m\times n$. $m\times n$, more commonly written mn. and,

**Square numbers**are of the form, $n\times n$

If $m = n$, then $mn = m^2 = n^2$. $mn = m^2 = n^2$, a square number.

For example $7^2 = 49$.

But if m not equal to n, then mn might be a rectangle.

For example, $2 \times 18$
