well i know the length is 10 and the width is 7

Answer:

[tex]w(w+3)=70[/tex]    

Step-by-step explanation:

Let w be the width of the rectangle.

We have been given the length of the rectangle is 3 in. longer than the width. So the length of the rectangle would be [tex]w+3[/tex].

We are also told that the area of a rectangle is 70 in². We know that area of rectangle in length times width. We can represent the given information in an equation as:

[tex]w(w+3)=70[/tex]

Therefore, the equation [tex]w(w+3)=70[/tex] can be used to find the width of the rectangle.
