For this case we have that by definition, the area of a rectangle is given by:
Where:
a, b: They are the dimensions of the rectangle.
In the statement we are told that "The area is greater than 12 square inches", then:
Also we have:
Substituting we have:
Dividing between 2 on both sides:
Finally we have:
ANswer:
Option 3
The solution for given expression is
Given that we have to divide,
---- (A)
Let us first factorize each term and then solve the sum
Using
----- (1)
----- (2)
---- (3)
---- (4)
Now substituting (1), (2), (3), (4) in (A) we get,
To do division with fractions, we turn the second fraction upside down and change the division symbol to a multiplication symbol at the same time. Then we treat this as a multiplication problem, by multiplying the numerators and the denominators separately.
On cancelling terms we get,
Thus option 3 is correct
