The coordinates of the vertices of △ABC are A(1,4), B(-2,-1), and C(-3,-2). The height h to side BC is √2, and b is the length of BC. What is the area of △ABC?
I don't really know how to approach or start this problem, so if you can help, please do! Thanks!

I'm not really sure if I should use the distance formula to find the distance between the 3 points or do something else. Thanks!
BC is the base , and h is the height
area of a triangle is ... 1/2 * b * h ... 1/2 * BC * √2
use the distance formula to find BC
