6 centimeters
Step-by-step explanation:
Area of a triangle is A = height x base / 2
So plug in what you know.
42 = (14 x b)/2 get rid of the 2 by multiplying both sides by 2 which gives:
84 = 14 x b get rid of the 14 by dividing both sides by 14
b = 84/14
b=6 cm
2, -3
4 units down is -9, then a reflection over y axis makes -2 2 6 units up makes -9 -3
