The area of a parallelogram is 160. If the base is reduced to one-fourth its original length and its height is doubled, what is the new area?(1 point) Responses 60 60 80 80 160 160 320

1 answer

The new area can be calculated by first finding the new base length and height of the parallelogram after the changes are made.

Let the original base length be x and the original height be h.

Given that the area of the parallelogram is 160:

Area = base * height

160 = x * h

Given that the new base length is one-fourth its original length and the height is doubled:

New base length = x/4
New height = 2h

The new area can now be calculated as:

New Area = new base * new height

New Area = (x/4) * 2h
New Area = (x * 2h)/4
New Area = (x * h)/2
New Area = 160/2
New Area = 80

Therefore, the new area of the parallelogram is 80.

Correct answer: 80
