#1**+1 **

The scale factor for the two parallelograms is just the square root of the ratio of the areas =

sqrt (40/10) = sqrt (4) = 2

So....this means that each side of the larger parallelogram is 2 times that of the smaller

So......the perimeter of the larger parallelogram is also 2 times that of the smaller = 2 * 22 = 44 cm
