Mathematics

$11y^{6}$

Step-by-step explanation:

A monomial is a kind of algebraic expression having only one term.

For ex : $3x\ , 4b\ ,\ 6x^2y$ etc.

We know that ,

Area of rectangle = Length of rectangle x width of rectangle.

We are given that ,

Length of rectangle =11y^4

Width of rectangle =y^2

Then,

Area of rectangle = $=11y^4\timesy^2$

Using identity ,

$a^m\times a^n=a^{m+n}$

we have

Area of rectangle = $=11y^{4+2}$

⇒ Area of rectangle = $=11y^{6}$

Hence, the area of a rectangle $=11y^{6}$ [which is a monomial]
