Figure ABCDE has vertices A(−2, 3), B(2, 3), C(5, −2), D(0, −4), and E(−2, −2). Plot the points on your own coordinate grid and connect the points in alphabetical order. Decompose Figure ABCDE into rectangles and triangles.
Part A: How many triangles and rectangles did you make? (1 point)
Part B: Use Figure ABCDE created on your coordinate grid to find the lengths, in units, of Sides AB and AE. (4 points)
Part C: What is the area of Figure ABCDE? Show your work. (5 points)

Best ResponseYou've already chosen the best response.1you have to compute the difference between the xcoordinates or y.coordinates. For example: \[\Large \begin{gathered} AB = 2  \left( {  2} \right) = ... \hfill \\ AE = 3  \left( {  2} \right) = ... \hfill \\ \end{gathered} \]
