Idon’t understand this question

the area of a parallelogram is 240. if the base is reduced to one-fourth its original length and it’s height is doubled, what is the new area?

a. 30
b. 60
c. 120
d. 240

120 units² (Answer C)

Step-by-step explanation:

The area of a parallelogram of base b and height h is A = bh, and here

A = bh = 240 units².

Doubling the height would give us a new height of 2h, and taking a quarter of the original base (length) would give us a new base (length) of b/4.

                                                                    240 units²

Solving A = bh = 240 units² for h yields

                                                                           b

and then substituting this result for h in the new equation

A = (2h) · (b/4) yields:

            240 units²                     2 · (240 units²)

     (2 · ) · (b/4), or = 120 units² (Answer C)

                    b                                       4

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
