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

 

 

cool cool cool
