$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

GIVEN :

Length of the rectangle = 15 cm.

Area of the rectangle = 135 cm^2.

TO FIND :

Perimeter of the rectangle.

SOLUTION :

Let's first find out the breadth of the rectangle.

Now,

Area of the rectangle = length × breadth

=> 135 = 15 × breadth.

=> Breadth = $\frac{135}{15}$

=> Breadth = 9 cm.

Now, let's find the Perimeter of the rectangle.

Perimeter of the rectangle = 2(length + breadth)

= 2(15 + 9)

= 2(24)

= 48 cm

$\boxed{\sf{Hence \: perimeter \: of \: the \: rectangle = 48cm}}$
