Question

The SI unit of length is meter. Suppose we adopt a new unit of length which equals to x meters. The area 1m^2 expressed in terms of the new unit has a magnitude.... a) x b) x^2 c) 1/x d) 1/x^2

Answer 1

Given :

SI unit of Length= meters.
New Unit of Length =x meters.
1m=1/x new units

SI unit of area :
A= 1m²             
  =1x1m²           
  =1/x*1/x     
  =1/x² 
So option (d) is correct answer 

Answer 2

Answer:

the answer is option D 1/x^2
