kotykmax [81]

Answer:

1.99 L

Step-by-step explanation:

The total liters of the water filled is 2 liters

But the family drank 11.73 liters

How should it be possible that the family drank is more than the total liters

So here we assume that the family drunk water should be in milliliters

Now the number of liters left is

= 2,000 ML - 11.73 ML

= 1988.27 ML

Now convert into liters which is

= 1988.27 ÷ 1,000

C. A parallelogram
Oxana [17]

If a parallelogram has an area of 7 square units, and the height corresponding to a base is (\frac{1}{4}) units, then the base is 28 units.

As per the question statement, a parallelogram has an area of 7 square units, and the height corresponding to a base is (\frac{1}{4}) units.

We are required to find out the base of the parallelogram.

To solve this question, we need to know the formula to calculate the area of a parallelogram, which goes as

Area of Parallelogram = (Base * Height)

Putting our data obtain from the question statement, in the above-mentioned formula, we can calculate the value of the base of our concerned parallelogram, i.e.,

7=(base*\frac{1}{4})\\or, base=(7*4)\\or, base = 28
Therefore, base of our concerned parallelogram is 28 units.

  • Parallelogram: In Euclidean geometry, a parallelogram is a four-sided, plane, closed figure (Quadrilateral) with two pairs of parallel, opposite sides.
