Answer:
Orthographic Projection is used for making the projects but Isometric Projection is used to have better understanding of the object.
Orthographic drawings are typically two dimensional views of an object. For instance, if you were designing a table, you would draw a top view, side view and a bottom view. Should these three views not fully explain the design of the table other views would need to be drawn. When drawing an perspective view in an orthographic manner, you would utilize a 45 degree triangle for the lines that extend back or forward from the vertical lines. This type of perspective is not a true perspective because you can measure the true length of all the details shown. An isometric drawing is meant to depict a 3D image of an object in what appears to be a perspective view. However, similar to an orthographic perspective, all of the lines in an isometric drawing can be measured to their true length. What makes it different from an orthographic perspective is that its angled lines are drawn at 30 or 60 degrees or divisions of them. Drawing this by hand you would use a 30/60/90 triangle.
In either case, both types of perspectives can be accurately measured with a ruler in order to know the objects measurements.
Step-by-step explanation:
we have that
A+B=B+A -------> is the same
so
B+A= (1-5) (-3+3) (4-5) (-5-2)
(2-4) (5-2) (-4+4) (4-5)
<h2>B+A= -4 0 -1 -7</h2><h2> -2 3 0 -1</h2>
Let's separate this shape into three parts. A smaller rectangle at the top, and one at the bottom, and a bigger rectangle in the middle.
The smaller rectangle at the top:
The equation to find the area of a rectangle is
(a = area, l = lenght, w = width)
a = l · w
Put in the values
a = 18 · 3
a = 54
Since the smaller rectangle at the bottom has the same length and width, it has the same area.
The bigger rectangle in the middle:
a = l · w
Put in the values
a = 8 · 9
a = 72
Now add all of the areas together to get the answer!
72 + 54 + 54 = 180
The answer is 180 :)

The answer is b because if you divide that’s what you get
