Question

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

Answer 1

ANSWER:

x^21

STEP-BY-STEP 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
