Question

1. calculate the length of CA using C = (1,6) = (x1,y1) and A = (2,1) = (x2,y2)

2. calculate the length of DB using D = (1.654,2.731) = (x1,y1) and B = (3,3) = (x2,y2)

3.multiple the two lengths, then divide by 2 to get the area

Answer 1

\[Length=\sqrt{(x2-x1)^2+(y2-y1)^2}\]\[\sqrt{(1-2)^2+(6-1)^2}\]
\[\sqrt{(1.654-3)^2+(2.731-3)^2}\]

Answer 2

thank you
