CHALLENGE ACTIVITY 2.10.1: Coordinate geometry. Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to pointsDistance. The calculation is:

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
