1st
C) is just 1/2xbxh

24.5=1/2 x bc x y
Where y is the shorted distance from A to BC

BC is now your new base and shortest distance is the height

Area of triangle = half x base x height
so length of base =7
Height=7
Half of 49 will be 24.5.

A(-6,2) B(1,2) as it is a horizontal line the difference we can see it as 7 units

C(-1,9)
as for area of triangle we are looking at half x base x perpendicular height
We can just take vertical difference of the y coordinates of C and AB which is 9-2=7 since AB is a horizontal line.
