Answer:
Yes, the dimensions will be 2x2
Step-by-step explanation:
When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same. 
Ex. 2x3 by 3x2 or QxD by DxW
The dimensions of the result will depend on the outer numbers. 
Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result

Answer:
a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
Step-by-step explanation:
From the above question, we know that 
Rui feng is 3 years old 
We are told that 
• Michael is 5 years old than Rui feng 
Micheal's present age is calculated as:
= 5 + Rui feng's age
= 5 + 3 = 8 years
• Vishal is thrice as old as Micheal
Vishal's present age is calculated as
= 3(Micheal age)
 = 3(8)
= 24 years.
The sum of their ages in six years time 
= ( 3 + 6) +( 8 + 6) + ( 24 + 6)
= 18 + 15 + 30
= 63 years 
Therefore, a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
