Answer:
44 square units
Step-by-step explanation:
The area of the 2 upper triangles is:
2 * ((1/2) * b * h) = 2 * ( (1/2) * 4 * 3) = 2 * 6 = 12
The area of the rectangle in the middle of the figure is:
b * h = 8 * 3 = 24
The area of the lower triangle is:
1/2 * b * h = 1/2 * 2 * 8 = 8
The area of the composite figure is:
Area of the 2 upper triangles + area of the rectangle + the area of the lower triangle = 12 + 24 + 8 = 44 square units (area is always given in square units)

Answer:
Weekly allowance $4
Step-by-step explanation:
Fred ended with $11. So, subtract $9 from washing the car.
$11 - $9 = $2
$2 Is the amount of weekly allowance Fred <em>hasn't</em><em> </em>spent yet. However, at the beginning of the week, Fred used half his allowance. This means $2 was what was left. So,
$2 × 2 = $4
meaning Fred had $4 in allowance at the beginning of the week.
