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.

A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
