Answer: b=13, t=29
Step-by-step explanation:
Substituting the first equation into the second,

1. Divide it into a triangle and a rectangle
2. To solve the area of the rectangle which is (length times width) do 2x9 = 18
3. To solve the area of the triangle which is (length times width divided by 2) do 2x4/2 =4
4. Area = 18 + 4, 22 square units
