we know that area of a rectangle=length*width length=area/width area=2.76 x 10^12 units² width=4.6 x 10^5 units length=2.76 x 10^12/4.6 x 10^5 ------> 6 x 10^6 units
perimeter of a rectangle=2*[length+width] width=4.6 x 10^5 units----> is equal to 0.46 x 10^6 units length=6 x 10^6 units
perimeter of a rectangle=2*[6x10^6+0.46x10^6]----> 12.92 x 10^6 units
