the area of a parallelogram is 120. of the base is reduced one-half of its original length, and it height is quadrupled, what is the new area
30
60
120
240**
They changed the test! Now, for the final question, the height is doubled, and the answer choices are all different. IE. 60 is not a choice for question 1. :(
Well, a square is a parallelogram
A =s^2
new A = (s/2)(4s) = 2 s^2
120 * 2 = 240
so yes, agree :)
Thank you Damon.
