A manufacturer is designing two rectangular game boards. The width of the smaller board is one-half the width of the larger board, and the length of the smaller board is one-sixth the length of the larger board. If the smaller board has area N, then what is the difference between the areas of the game boards, in terms of
N ?
A) 3N
B) 9N
C) 11N
D) 12N
E) 18N
For easy calculation at first consider-
Numerical value for wwidth and Length of the larger board and number is divisible
For larger board let us assume-
Length = 12
Width =4
therefore for smaller board
Length = \(\frac{1}{6}\) *12 = 2
Width = \(\frac{1}{2}\)* 4 = 2
(Plz note every square can be rectangle but every rectangle cannot be square and these numbers assumed
still hold valid for the statement)Therefore Area of Smaller Board= N = 4 and Area of Larger Board = 48
The difference between the areas= 48 -4 = 44
Now plug the value of N in the solution
Only option C satisfy
(Remember the we can put different value for Length and Breadth and the answer is remain the same, for easy calculation we take nos. that are divisible by 2 and 6)
