Step-by-step explanation:
Given Equation:

Actually the given equation is the 2nd equation of motion
i.e. 
where
because the astronaut jumps on the earth
and initial velocity 
to find time
, put the given value of
in the given equation, we get

it will take
to reach the ground if he jumps on the Earth
Let x= width
Length= 5x-4
2(x)+2(5x-4)=160
2x+10x-8=160
12x-8=160
+8. +8
12x=168
x=14
width=14
length= 5(14)-4=66
