What is the perimeter of the rectangle? Write your answer in scientific notation. The area is 2.76 x 10 pw12

MrRa [10]

We know that
area of a rectangle=length*width
length=area/width
area=2.76 x 10^12 units²<span>
width=4.6 x 10</span><span>^5 units
</span>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

the answer is
12.92 x 10^6 units

notice, it goes 4,6 then 4, 6 again, and so on and so on
based on whatever exponent it may have

now, you're being asked, what 214 will give? 4 or 6?
