Question

I need to know expression represents the area given the side and length side x7length x14

Answer 1

x^21

Explanation:

The area of a rectangle is given by the following formula:

`A=l\cdot w`

Therefore, we substitute and calculate the area, just like this:

`\begin{gathered} A=x^(14)\cdot x^7 \\ \\ A=x^(14+7) \\ \\ A=x^(21) \end{gathered}`

Therefore, the area of the rectangle is equal to x^21
