a rectangular lawn is 16 yards by 28 yards. it would cost $4.63 per yard to install a fence around the lawn. how much would it cost to put a fence around the lawn?

The figure 1 shows the counter example.

Step-by-step explanation:

Consider the provided information.

It is given that the points a b and c are noncollinear and we need to give a counter example

Noncollinear Points: Points not lying in the same straight line are called Noncollinear Points.

Noncoplanar Points: Points not lying in the same plane are called Noncoplanar Points.

we need to give a counter example;

Consider the figure 1:

The point A, B, and C are noncollinear points and drawn in a same plane

through all three points.

Hence the figure 1 shows the counter example.
