Triangle CDE, with vertices C(-8,-7), D(-2,-8) and E(-5,-2), is drawn on the coordinate grid below. What is the area, in square units, of triangle CDE?

Area = 24.75 sqr units

Step-by-step explanation:

You will need these formulas:

Midpoint =

Area = b x h

Let us treat CD as the base. Find the length of the base with the distance formula. Use the coordinates for points C & D.

The base is .

The height is the distance between point E and the midpoint of line CD.

Midpoint of CD = = (, )

Use the distance formula to find the height.

Find the area with the two distances that were found.

Area =

Area =

Area = 24.75 sqr units
