maarriinnaaaa · Answer

When doubling the dimensions of a parallelogram, the perimeter is doubled, the area is multiplied by 2 squared...or 4

maarriinnaaaa · Answer

14 is  the starting area.  The formula says to multiply the area by 4 when the dimensions are doubled.

maarriinnaaaa · Answer

the idea is that all four sides are doubling in length, hence multiplying the area by 2^2, or 4, as opposed to just 2.

so you would do 14(4) and get 56
