Question

If the coordinates of a parallelogram are Q(3, -2), R(7, -2), S(9,3), and T(5,3), the area of the parallelogram is:

Answer 1

Answer:

  20 square units

Step-by-step explanation:

The figure is 4 units wide and 5 units high, so its area is ...

  A = bh = 4·5 = 20 . . . . units²

_____

The width is the difference between x-coordinates on the same side of the figure: 9 -5 = 7 -3 = 4.

The height is the difference between the y-coordinates: 3 -(-2) = 5.
