x ≈ 12.182
Step-by-step explanation:
1 - 2lnx = - 4 ( subtract 1 from both sides )
- 2lnx = - 5 ( divide both sides by - 2 )
lnx = 2.5
x = ≈ 12.182 ( to the nearest thousandth )

Answer:
132
Step-by-step explanation:
Divide it into 2 shapes : a triangle and a rectangle.
The triangle's base length is 20-(8+6) = 6
The height is 10-6 = 4
The triangle's area = 6*4/2 = 12
The rectangle's area is 6 * 20 = 120
Add the two together, and you get 12+120 = 132
