Step-by-step explanation
bruh...
1. Divide 140 by 6 and you get 23.3 repeating
2. When you multiply 23 times 6 you get 138. (not enough seats)
3. So, you would need to have at least 24 cars in order for everyone to go on the trip. (24 x 6 = 144 seats)
Option B: The area of the trapezoid is 157.5 m²
Explanation:
We need to determine the area of the trapezoid.
The area of the trapezoid can be determined by the formula,

where h is the height, a and b are the base of the trapezoid.
From the figure, it is obvious that
,
and 
Substituting these values in the formula, we have,

Simplifying the terms, we have,

Multiplying the terms in the numerator, we have,

Dividing, we get,

Thus, the area of the trapezoid is 157.5 m²
Hence, Option B is the correct answer.
Answer:
the answer will be 6 or 10
