Question

A city planner is mapping out some new features for a triangle park. She sketches the park on a grid paper. The coordinates of the vertices of the park are (1, 1), (1, 4), and (-3, 4).

Answer 1

Answer:

Perhaps, she is interested in finding the area enclosed by this triangular park.

Step-by-step explanation:

The area of the triangle enclosed by the three points

A(1,1), B(1,4) and C(-3,4) in this question will be given by

|Ax ( By  − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2  

=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.
