Okay, so keeping mind that the equation for area is A = L x W, look at the measurements you already have. 5.5 x 10^5 is the length, and 4.2 x 10^4 is the width. Switch them into full form and use a calculator to multiply the two for the area in meters.
550000 x 42000 = 23100000000, which in scientific form is 2.31 × 10^10. So that's answer one.
For the second, in kilometers, just take the full measurement you already have, 23100000000 m, transfer it into kilometers, 23100000 km, and then find its scientific notation, 2.31 × 10^7. That's answer two.
To answer the last question for which is more suitable, just consider what number you'd prefer to look at: a bigger number or a smaller one. Since the kilometer measurement number is smaller, its correct.
Summarily, the answers are 2.31 × 10^10, 2.31 × 10^7, and square kilometers, in that order.

Step-by-step explanation:
Let the first angle be 
degrees
Let the second angle be 
degrees
Let the third angle be 
degrees
It is given that sum of angles is 
degrees.
so,
...(i)
It is given that sum of the measures of the second and third angles is two times the measure of the first angle.
...(ii)
It is given that the third angle is 26 more than the second.
...(iii)
using (ii) and (iii),
using (i),(ii) and (iii),
Answer:
in this equation, x = -1
Step-by-step explanation:
hope this helps!
Multiply the first equality by 3/2 and you get the second
There are thus an infinite number of solutions : x can be any number and y=2-3x/4
The formula for the triangular sequence is Xn=n(n+1)/2
So X25=25(25+1)/2=325
