Does dose anyone know how to solve this?

Width of rectangle = 6 m

Length of rectangle = 11 m

Step-by-step explanation:

Let width of rectangle = w

Length of rectangle = 3w-7

Area of rectangle = 66 m²

We need to find length and width of rectangle

The formula used is:

Putting values and finding w

Solve using quadratic formula:

We have a=3, b=-7, c=-66

Putting values and finding w

We get values of w as w=6 and w=-3.6

As we know width cannot be negative, so considering w = 6

So, Width = 6

Length = 3w-7 = 3(6)-7 = 18-7 = 11

So, Width of rectangle = 6 m

Length of rectangle = 11 m

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
