Polygon abcd has the following vertices: a(−3, 3), b(5, 5), c(5, −4), and d(−3, −4) calculate the area of the polygon. 52 units squared 56 units squared 64 units squared 72 units squared yes it is multiple choice answer for 5o points 

To solve this problem you must apply the proccedure shown below:

1. When you plot the given points, you obtain a trapezoid, therefore, you must apply the formula for calculate the area of a trapezoid, which is:

Where is the larger base, is the smaller base and is the height.

2. The dimensions are:

3. Substitute values:

The answer is:

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
