Question

Write an inequality that represents the missing dimension x

Answer 1

For this case we have that by definition, the area of a rectangle is given by:

$A = a * b$

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:

$A> 12$

Also we have:

$a = 2\\b = x$

Substituting we have:

$2x> 12$

Dividing between 2 on both sides:

$x> \frac {12} {2}\\x> 6$

Finally we have:

$x> 6$

ANswer:

$x> 6$
