id say its a rhombus. all the other shapes can have right angles
The equation showing the relationship between w and t is 
From the table, we have the following points:
(0,0) and (1,4)
Start by calculating the slope (m)

So, we have:

Simplify the numerator and the denominator

Divide 4 by 1

The equation is then calculated as:

This gives

Simplify

Hence, the equation is

Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,

x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
