Answer:
72m^2
Step-by-step explanation:
Conevert the lengths into what they really are
Length of Patio:12
width of patio:6
Soooo.....
multiply
12x6=72
The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: 
The page dimension is:


The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square
The margin of 0.75 on either sided means the usable dimension is:

The dimension of India is:


The longest side in India's dimension is:

From Uche's book, the longest dimension is:

So, the scale equation is:
k * longest length of Uche's book = longest side of India
This gives:
