If the figure below is 128inches squared what is the perimeter
4
5x+7
it's a four sides object

Step-by-step explanation:

Assuming that the shape is a rectangle:

The area of a rectangle can be found with the following:

where is the length of the rectangle and is the width of the rectangle.

From the problem statement, we know that one side of the rectangle is and the other side is , and the rectangle has an area of , so we can plug these values into the above formula to solve for :

This means that the side lengths of the rectangle are and (plugging back into the original side length).

The perimeter of a rectangle can be found with the following:

Plugging in the values we have previously, we'll get the following:

The first thing we must do for this case is to find the equation of the line for CD.

We have then:

Where,

Substituting values:

We choose an ordered pair:

Substituting values:

Rewriting:

Then, we look for the equation of the line perpendicular to CD.

We have an equation of the form:

As the lines are perpendicular:

Then, as the line passes through the point (-1, 6) then substituting, we can find the value of b:

Then, the equation of the line is:

b. y = -0.5x + 5.5
