Calculate the area of triangle wxy with altitude yz, given w(2, -1), x(6, 3), y(7,0), and z(5,2)

The area of the triangle WXY is 8.49 square units.

Step-by-step explanation:

I have graphed the points in the figure attached.

The area of any triangle is

where is the height of the triangle, and is the base.

In our case the base of the triangle is WX, and the height is YZ.

Now

and since

Now we find the height YZ:

Now we are ready to find the area of the triangle:

Which, when simplified as a decimal, is 8.49 square units.

the answer is d. 75%
