Width is 6; Length is 24
Explanation:
Key points:
Rectangle shape
Width
Let the area be A=144
Let the width be W
Let the length be L
Known:
Given:
To determine the value of L
Substitute (2) into (1) giving
Multiply both sides by 4
Taking the square root of each side
To determine the value of W
But
Divide both sides by 24

Since the banner is in the shape of a rectangle, and we are asked to find the area of the banner, we are therefore asked to find the area of the rectangle.
The formula for an area of that shape is length multiplied by its width.
The question doesn't specify what the length and width are. However, it does say that the width is
Let's say the width was "x".
If the length is 4 times larger than the width, then we can multiply the width, x, by 4. This will give length
Now we have values for both length and width:
Recall that the area of the rectangle is length times width, which means
But wait a minute, we already know what area is. It's 144.
Simplify for x.
