Answer:
x = -12
Step-by-step explanation:
4/3x + 12 = - 4 (multiply 3 both side)
4x + 36 = - 12 (minus 36 both side)
4x + 0 = -12
4x = -12 - 36
4x = - 48 (divide both side)
4x ÷ 4 = x
-48 ÷ 4 = -12
Answer: x = -12
First use Pythagoras theorem to find the remaining length of the base.
Then multiply the base with the altitude and divide that by 2 and you'll get the area
