Let, the length be l and breadth be b.

So, 2(l + b) = 26

Or, l + b = 13

Or, l = 13 - b

So, we may write like this,

Area = l * b

Or, l * b > 30

Or, l (13 - l) > 30

Or, 13l - l^2 > 30

Or, l^2 - 13l + 30 > 0

Or, l^2 - 3l - 10l + 30 > 0

Or, l(l - 3) - 10(l - 3) > 0

Or, (l - 3)(l - 7) > 0

Or, l - 7 > 0

Or, l > 7.

Now, putting the value of l,

We get, l * b > 30

Or, 7 * b > 30

Or, b > 30/7

➡️ Therefore, we get,

Length > 7

Breadth > 30/7

That's it..

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x? x =

sukhopar [10]

Start with

$2(x-3)+9=3(x+1)+x$

Expand both parentheses by multiplying both terms by the number outside:

$2x-6+9 = 3x+3+x$

Sum like terms:

$2x+3 = 4x+3$

Simplify the "+3" on both sides:

$2x = 4x$

Subtract 2x from both sides:

$2x=0$

Divide both sides by 2:

$x=0$
