From the text you can derive the following equations:
(1) A = bh/2 = 8
(2) and h = b+6
Fill in h in (1):
b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.
Answer:
is it 38? cause 12 times 3 is 36 add 2 which is 38
Y= -5x+3 is the equation that is perpendicular to line AB with the point (1,-2)
We are given the following two points.

Let us find the distance between these two points.
Recall that the distance formula is given by
