The area of the given polygon which is a rectangle is; 28 sq. units
We are given the coordinates of the polygon as;
A(3,7)
B(5,7)
C(3,-7)
D(5,-7)
Now, by close inspection of the coordinates, we can tell that this polygon is a rectangle. Thus, we can deduce that;
AB = 5 - 3 = 2
CD = 5 - 3 = 2
BC = 7 + 7 = 14
AD = 7 + 7 = 14
Formula for area of a rectangle is;
A = Length * Width
A = 14 * 2
A = 28 sq. units
