(3.9 * 10^33)(1.55 * 10^7)
3.9 * 1.55 = 6.045
10^33 * 10^7 = 10^40
6.045 * 10^40 <=== ur answer for the 1st one
1.6 * 10^-3 = 1.6 * 1 / 10^3 = 1.6/1000 = 0.0016 <== its probably this one...the 1.6 * 10^-3

20 feet
Step-by-step explanation:
Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.
To find perimeter, we need to add up all the sides.
