Answer:
![- 8(y - 2) = 160 \\ - y + 2 = 20 \\ - y = 18 \\ y = - 18](https://tex.z-dn.net/?f=%20-%208%28y%20-%202%29%20%3D%20160%20%5C%5C%20%20-%20y%20%2B%202%20%3D%2020%20%5C%5C%20%20-%20y%20%3D%2018%20%5C%5C%20y%20%3D%20%20-%2018)
Step-by-step explanation:
Just because before y there is negative "-" thus youve got to put it before 18. Eventually the answer is -18,not 22
Addition because it asks how much
Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
