Set up the equation to find the AREA of the SMALL rectangle with a length of (x) and width (x+7)

Igoryamba

<u>Answer:</u>

<u>Step-by-step explanation:</u>

To find the area of a rectangle, we have to multiply the length with the width.

In the question, the given length is 'x' and the width given is 'x +7'

So, the area would be

( $x$ ) x ( $x + 7$ )

The area = $x^{2} + 7x$

So, the equation to find the area of such a rectangle would be:-

( $x$ ) x ( $x + 7$ )
