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

anonymous · Answer

is it 14 @j.thain

anonymous · Answer

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

anonymous · 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.
