From the given vertices, the area of the polygon is 28.
<h3>Rectangles</h3>
The rectangle is a quadrilateral. The classification for quadrilaterals is given by the length of sides and angles. For a rectangle, the opposite sides are equal and parallel and their interior angles are equal to 90°.
A rectangle is a geometric figure that has 4 sides called: base and height. Due to its characteristics, the rectangle presents two bases (B) and two heights (H).
The area of a rectangle is given by the multiplication between the base and the height.
First, you should plot the points, then see image 1.
From the figure, it is possible to see that the bases ( AB and CD) = 5-3=2
and heights (AC and BD) =-7-(-7)=7+7=14. Thus,
A= B*H= 2*14=28

notice that all you do is simply multiply the terms of either one by the terms of the other sequentially, then add like-terms.
Answer:
57 square units.
Step-by-step explanation:
You need the area of each side, then you add all of them together. (5*3.5)+(3*3.5)+(
3*4)+(
3*4)+(4*3.5).
In 1st fig
A=5×x(let)
9=5×x
in 2nd fig
A=10×2x(5 is doubled so ×also doubled)
A=10×2×9÷5
A=36
