Question

If the area of the rectangle whose breath is X cm is 2x² cm² then the peremiter of the rectangle is what​

Answer 1

Answer:

6X

since length= area÷breadth

= 2X

therefore perimeter=2×(l+b)

= 2×(2X+X)

=2×3X=6X

Answer 2

Given:

Breadth = x cm

$area = 2 {x}^{2}$

To find:

Perimeter = ?

Method:

$area = length \times breadth$

$2x {}^{2} = length \times x$

$\implies \: length = \frac{2 {x}^{2} }{x} = 2x$

Now using perimeter of rectangle formula,

$perimeter = 2(l + b)$

Substitute values of length and breadth,

$perimeter = 2(2x + x)$

$perimeter = 2 \times 3x$

$\therefore { \boxed{ \large{perimeter = 6x}}}$
