What happens to the area of the parallelogram if the base is increased 2 times and the height is halved?
पर्याय
Decreases to half
Remains the same
Increase by two times
None
उत्तर
Remains the same
Explanation;
Hint:
Area = b × h sq.units
New base = 2 × old base
New height = `1/2` × old height
New Area = New base × New height
= `(2 xx "b")1/2 xx "h"`
= bh
= old Area
