Answer:
a=48 units^2
Step-by-step explanation:
The area of a rectangle can be found using: 
a=bh
We know the base is 6, and the height is 8, so we can substitute them in 
a=6*8
a=48 
Area uses units squared, so, 
a=48 units^2
 
        
                    
             
        
        
        
Answer:
x=0
Step-by-step explanation:
120521x=0
x=0/120521=0
 
        
             
        
        
        
Suppose that both planets are spherical. radius of Saturn =142984/2=71,492
Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10
Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10
Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km
