<u><em>The complete question is</em></u>
The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. What is the area of one trapezoidal face of the figure?
we know that
The area of a trapezoid is given by the formula
where
b_1 and b-2 are the parallel sides
h is the height of the trapezoid (perpendicular distance between the parallel sides)
we have
substitute the given values in the formula
Answer:
The answer is (Choice C) It is just right.
Step-by-step explanation:
<u><em>The question is incomplete, so the complete question is below:</em></u>
Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water. Peggy made a 12-liter batch of iced tea with 90 tea bags. What will Kermit think of Peggy's iced tea? Choose 1 answer: (Choice A) It is too strong. (Choice B) It is too weak. (Choice C) It is just right.
Now, to find which of the choice is correct.
So, we find first the unit rate of Peggy's iced tea bags per liter:
If, Peggy made a 12-liter batch of iced tea with 90 tea bags.
Then, Peggy would made a 1-liter batch of iced tea with =
Now, to get the unit rate of Kermit's iced tea bags per liter:
If, Kermit made a 2 liter of iced tea with 15 tea bags.
Then, Kermit would made a 2 liter of iced tea with =
<u><em>Thus, the quantity of tea bags per liter is same of both Kermit and Peggy.</em></u>
<u><em>Hence, Kermit will think of Peggy's iced tea that </em></u><u><em>it is just right</em></u><u><em>.</em></u>
Therefore, the answer is (Choice C) It is just right.
