答案和解析

  Correct Answer: B

  Here's Why:

  Figures in a Coordinate Plane

  The figure provides all the information you need to answer the question.

  What Is the Question Asking?

  You are asked to figure out the area of a triangle that is defined by the points in a coordinate plane.

  What Do You Know?

  The triangle in the figure is a right triangle with the right angle at the lower left.

  Because it is a right triangle, its base and height are the two sides that form the right angle.

  The area of a triangle isbh.



  The base of the triangle extends from point (0, 0) to point (5, 0). So it is 5 units long.

  The height of the triangle extends from point (0, 0) to point (0, 3). So it is 3 units long.

  Area =bh=(3)(5)= (15)= 7.5

  Difficulty: Medium

  Question Type: Standard Multiple Choice
