The parallelogram's area is 30 because L x W is the formula of finding the area of the parallelogram so.... 6 x 5 = 30 square dm
and...
the circle's is 78.5 because pi x r x r is the formula of finding the area of the circle so... 3.14 x 5 x 5 = 78.5
so the smaller area of the two is the area of the parallelogram
and subtract the two areas to find how much smaller the area of the parallelogram is than circle
and the parallelogram is 48.5 smaller than the area of the circle
