The area of shaded region will be equal to the difference of the areas of the two rectangles , that is equal to 48 u² .
The area of rectangle is length × breadth .
The dimensions of bigger rectangle is (x+3)(x-4) and that of smaller one is 3 × x .

So that ,

$\longrightarrow$ ar(bigger) - ar(smaller) = 48

$\longrightarrow$ [ (x+3) (x-4)] - 3(x) = 48

$\longrightarrow$ [ x² - 4x +3x -12 - 3x ] = 48

$\longrightarrow$ x² -4x -12 -48 = 0

$\longrightarrow$ x² - 4x - 60 = 0

$\longrightarrow$ x² - 10x + 4x - 60 = 0

$\longrightarrow$ x( x -10) +4(x -10) = 0

$\longrightarrow$ (x +4)(x-10) = 0

$\longrightarrow$ x = -4,10

$\longrightarrow$ x = 10

<h3>Hence the required answer is 10.</h3>
