Find the area of triangle ABC, whose co-ordinates are A(4, -6), B(3,-2) andC(5,2) then find the length of the median AD?​

Answer»

Answer:

6 UNITS

Step-by-step explanation:

to to FIND the length of the median AD,

we have to USE midpoint formula and distance formula.

first we will use midpoint formula

that is,

(x1+x2 , y1+y2) = (3+5 , -2+2) = ( 8 , 0 )

( 2. 2. ) ( 2. 2. ). (. 2. 2 )

= ( 4, 0)

now we will use distance formula

that is ,

= ✓(x2-x1)^2 + (y2-y1)^2

= ✓( 4-4 )^2 + [0-(-6)]^2

= ✓(0)^2 + (6)^2

=✓36

= ✓6

= 6 units.
