\

The area of the rectangle is $\"\"$ .

\

Observe the graph:

\

The length of the rectangle is $\"\"$ .

\

The breadth of the rectangle is $\"\"$ .

\

Formula for area of the rectangle is $\"\"$ .

\

$\"\"$ (Substitute $\"\"$ , $\"\"$ and $\"\"$ )

\

$\"\"$ (Multiplication: $\"\"$ )

\

$\"\"$ (Divide each side by $\"\"$ )

\

$\"\"$ (Cancel common terms)

\

$\"\"$ (Add $\"\"$ to each side)

\

$\"\"$ (Substitution: $\"\"$ )

\

$\"\"$ (Apply square root on each side)

\

$\"\"$ (Cancel square and root term)

\

$\"\"$ (Substitute: $\"\"$ )

\

$\"\"$ (Subtract $\"\"$ from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ and $\"\"$ (Separate solutions)

\

$\"\"$ and $\"\"$ (Simplify)

\

Therefore, Length can not be consider negative value.

\

Therefore, the solution is $\"\"$ .

\

$\"\"$

\

The solution is $\"\"$ .
